Learn how to ace your Genetech interview: review your CV, know your qualifications, research the company and industry trends. Highlight your strengths, be authentic, dress appropriately, ask questions, and stay positive. Interview Tips The key to a successful job interview is in the preparation. Review The first thing you must do is look over your CV. If you have been invited to an interview, it is because we found your CV impressive. Qualifications It may sound simple, but know your qualifications. Interviewers will have an interest in modules you’ve covered and projects you have worked on. Think about how you can use your qualifications, skills and experience to prove that they align with our job description. Research Conduct some research about Genetech and specifically the role you are interviewing for, the interviewers will expect you to know a bit about the firm, and why you are interested in working for us. Future If you are aiming to pursue a career with Genetech, then you must have a good understanding of what is happening in the industry and how this may influence your future. Notes If it helps, you can take notes to your interview. There is nothing wrong with referring to notes but ensure you do not to read directly from them throughout the interview. Strengths We will be assessing your strengths throughout the interview. This will allow us to identify how you may perform in the role, and it makes it a much more enjoyable experience. This also provides you a great opportunity to reflect on what you are good at. At the interview, we want to get to know the real, authentic you. Thus, whilst you may want to learn about Genetech and go through your previous experiences ahead of your interview, there is no need to come with prepared responses. Furthermore, the examples you use when answering questions do not always have to be work based. Feel free to talk about relevant personal experiences where appropriate. The questions may be tapping into your strengths and there is no ‘correct’ thing to say. Thus, answer honestly based on what feels most natural to you. Impression You can create a good impression by knowing who you are going to meet and arriving on time. The interviewers will also be expecting you to wear suitable business wear. Use I Use ‘I’ instead of ‘We’ even if you talk about something you have done as a team. Keep in mind that we are interested in hearing about your achievements and what your contributions were. Body Language Maintain eye contact but you do not need to stare, and smile and enjoy your interview with a positive attitude. Moreover, relax and do not rush your answers. It is fine if you need a moment before answering a question. Be conscious of your hand use and avoid fidgeting with props, such as a notebook or pen, because it can make you lose concentration. If you make a mistake at the interview, do not worry because nobody is perfect. Worrying about your mistakes will have a negative impact on your performance. Question Do not be afraid to ask questions especially if you are not sure about something. It may demonstrate you have done your research and are genuinely interested. Be Positive Let go of the negative things in the past, aim positively but expect nothing in the future, and enjoy every moment without any attachment.

Explore Genetech’s DNA typing quality control, upholding international standards with expert staff, cutting-edge methods, and stringent error checks. Quality Control DNA typing is a highly specialised procedure which requires knowledge and skill. Furthermore, for DNA typing evidence to be acceptable in a Court of Law, it has to meet certain quality standards, which have been well documented and followed by forensic DNA laboratories worldwide. Accordingly in 2010, we became the first DNA typing laboratory in Sri Lanka to achieve ISO 15189:2007 (now 15189:2012) accreditation from Sri Lanka Accreditation Board (SLAB). We at Genetech are proud to announce that every step of our DNA typing process meets these international standards. At Genetech, our quality standards cover all aspects of DNA typing, including qualified and experienced personnel, the latest equipment, and the best of chemicals and reagents. The entire process is performed to generate error-free results which can be verified by any laboratory in the world. Personnel: Genetech has the most experienced and qualified personnel in the field of DNA typing in Sri Lanka. They have pioneered DNA typing in this country, and have laid the foundation for the application of this technology in Sri Lanka. Equipment: We are a fully equipped organisation which has the ability to perform automated fragment analysis in the exact manner required by the standards. Our equipment are regularly calibrated to ensure error-free functioning. Laboratory management: All aspects of laboratory management and documentation are performed to meet the ISO 15189 standards. Aspects of confidentiality, security and independence have been diligently maintained. Technical quality: The type of DNA testing done by us is the latest, most accepted method known as Polymerase Chain Reaction (PCR) based analysis of Short Tandem Repeats (STRs). This method is presently accepted by the forensic community as the method of choice because of its sensitivity, accuracy, rapidity and cost effectiveness. The type of genetic test: STR loci (genetic locations) which are tested by us are those that are well-studied and regularly used by the forensic community. These include loci found on autosomes, and X and Y chromosomes. The STR loci tested by us are among the most accepted, internationally. These STR loci have also been tested for their suitability to be used for the Sri Lankan population, and they have been proven to be statistically suitable. There is also an established Sri Lankan population database for these loci which enables such DNA evidence to be presented to a Court of Law. In addition to STR testing, we also conduct mitochondrial DNA analysis as required, to assist tracing of maternal lineages. Error minimisation: In order to minimise the possibility of error, we will maintain standards of validation and verification. The analysis of casework samples will be done alongside internationally used standard human DNA, and the results of the casework analysis will be subject to comparison with these DNA standards. Negative controls will be run at every step of the analysis procedure in order to ensure that no cross-contamination of DNA has occurred. Reporting: Once DNA typing results are generated, they are stored in both a graphic format as well as in a numerical format. An individual's DNA profile can be submitted to a Court of Law in both formats. Our scientists can provide statistical interpretation of the results and express the accuracy of the test by statistical means, using data generated from the Sri Lankan human population databases. In order to be valid in a Court of Law, DNA evidence must be supported by statistical data. This data is obtained only by establishing a population database for the population group that is being tested. Therefore, only Sri Lankan population data can be used for such analyses.

Discover Dr. Maya Gunasekera’s legacy: the visionary who transformed Sri Lanka’s biotech landscape through DNA forensics and diagnostics at Genetech. Dr. Maya Gunasekera Founder of Genetech 1961 - 2006 Dr. Maya Gunasekera founded Genetech in 2002 to develop the field of biotechnology in Sri Lanka. She pioneered the use of DNA testing in forensic casework in Sri Lanka, and was involved in almost all DNA typing tests done in Sri Lanka until the time of her death. Research teams led by Maya developed the first DNA probe for the malaria vector, Anopheles culicifacies, introduced a new molecular test for the early diagnosis of dengue, pioneered genetic work on the Sri Lankan elephant and resolved the taxonomic status of a fruit bat species complex. In 1999, Maya gave expert evidence on DNA typing for the Hokandara murder trial making history as the first court case to accept DNA evidence in Sri Lanka. Maya had been involved in many national and international ventures. She served as a consultant for several committees of the Government Ministries, including the National Task force for Dengue prevention and control. At the National Science Foundation, Colombo, she served as the Chairperson of the Working Committee on Biotechnology. She also served as the Governor for International Centre for Genetic Engineering and Biotechnology (ICGEB) representing Sri Lanka, and as the coordinator for the drafting of National Policy and Guidelines for the safe use of Recombinant DNA Technology in Sri Lanka. Maya was not only a dedicated researcher but also an excellent teacher. As a senior lecturer in the Department of Chemistry, she co-coordinated the development of the syllabus for the first BSc Special degree programme in Molecular Biology and Biochemistry offered at a university in Sri Lanka. She taught people from various walks of life and delivered numerous lectures to police officers, lawyers, doctors and school children. She primarily focused on teaching and sharing her expertise on the application of DNA technology. Even when she was not in the best of health, she continued to do her duty towards society with immense courage and dedication. She received many awards in appreciation of her work both by local and international bodies. The International Foundation for Science in Sweden awarded their Jubilee Award to Maya in 2003 in recognition of her work. The Third World Academy of Sciences, Italy and the NSF, Colombo together awarded her the Young Scientist Award in Biology in 2002. Maya received one of the David Fussy Alumni scholarships, granted to only three persons per year from all the Commonwealth countries. Subsequently, she obtained a PhD in Molecular Parasitology from the National Institute for Medical Research in Mill Hill, London. The award for excellence in research by the University of Colombo, NSF – Sri Lanka Merit Award for Biotechnology, British Council Assert Award and President’s Research Bonus Award were also among the long list of her achievements. Prior to obtaining her PhD, Maya studied at Visakha Vidyalaya, Colombo and obtained her BSc degree with First Class Honours from the University of Colombo. She also worked as a Research Assistant at the Malaria Research Unit of the Department of Parasitology, Faculty of Medicine, University of Colombo. Anchor 1

Discover specialized DNA typing services at Genetech, including paternity tests and forensic analysis, for precise identification and familial verification in Sri Lanka. DNA Typing Our passion to improve We pioneered the use of DNA typing for human identification for forensic casework and analysis of family relationships including parentage testing. We are a major supplier of this technology to the medico-legal community and the judicial system in Sri Lanka. Our reputation for integrity and reliability has made us the main provider of forensic DNA testing in the country. Over 4000 cases of disputed parentage and another 4000 criminal cases have had the advantage of DNA evidence through Genetech. What is DNA typing? DNA typing is a method of identifying individuals from the differences in their DNA. It is used for forensic casework as well as for determining familial relationships between individuals including paternity, maternity and siblingship. Advantages of DNA typing The science of DNA typing relies on technology that allows an individual's DNA to be examined and analysed. A person's DNA is unique: no two individuals (with the exception of identical twins) have the same DNA. Every cell in a person's body has the same DNA. Hence, DNA taken from any part of the body from the same individual will always be the same. DNA typing can be performed from many types of biological specimens including blood, saliva, sperm cells, muscle, teeth and bones. Thus, a person's DNA can be typed from very little tissue or body fluid. DNA typing is used for two major purposes: Identification of individuals from biological samples: This is mainly done in forensic casework, where it is possible to determine the identity of a criminal by typing the DNA left behind at the scene of the crime. Determination of familial relationships: This includes paternity testing, maternity testing, sibling testing, grand-parent testing, and even the identification of mutilated bodies. DNA typing is the best method of identifying individuals and determining familial relationships due to many reasons. It is extremely sensitive: with even a very small amount of tissue, the test can be performed successfully. It is also very accurate: it can give a test result with a very high degree of certainty. It is very reliable: the likelihood of obtaining a false result can be minimised, and the likelihood of making an error in the conclusion can be calculated. How does DNA typing work? In the DNA typing process, a DNA banding pattern or profile of an individual is first obtained from a tissue sample. The DNA profile is observed in the form of a set of DNA bands known as alleles. Each person has a maximum of two specific alleles for a given genetic location. This DNA profile is compared with the profile obtained from a sample taken from the scene of a crime. If the alleles in the two profiles match, then it can be said that the sample taken from the scene of the crime is from the individual that was tested. DNA typing services Child custody and maintenance: In cases where one parent is claiming the custody and maintenance of a child and the other parent is refusing to accept parentage. Proof of adultery: Especially in divorce cases where the paternity of the child is suspect, and the wife is being accused of adultery, DNA typing can be used to determine whether the husband is the father of the child. View all Cost We are happy to announce that after much research and optimisation, we have streamlined our DNA typing methods, and we are therefore able to provide DNA typing services at a reasonable cost. We perform the same DNA typing tests which are used by internationally recognised laboratories, and maintain the same standards of quality so that the conclusions made by us can be verified by any accredited forensic DNA typing laboratory in the world. Contact us View Price List Quality control DNA typing is a highly specialised procedure which requires knowledge and skill. Furthermore, for DNA typing evidence to be acceptable in a Court of Law, it has to meet certain quality standards, which have been well documented and followed by forensic DNA laboratories worldwide. Accordingly in 2010, we became the first DNA typing laboratory in Sri Lanka to achieve ISO 15189:2007 (now 15189:2012) accreditation from Sri Lanka Accreditation Board (SLAB). Read more Accuracy of evidence DNA testing is the most accurate and reliable means of identity verification and parentage testing. The degree of accuracy of the test will depend on the genetic diversity of the Sri Lankan population as well as the number of genetic locations (STR loci) which are tested. There is no mandatory number of STR loci required for a test, but the testing of nine STR loci or more is generally considered to be sufficiently accurate. We test up to 15 STR loci. Read more Ethical Guidelines DNA typing is performed ethically only with the informed consent of the individual whose DNA is being typed. The persons concerned will be informed about the consequences of the test. Where such consent cannot be given such as in the case of minors, the consent of the guardian has to be obtained. We will not undertake samples for parentage testing without written consent from all living parties who will be tested.

Early diagnosis is crucial for canine health. Our PCR-based tests detect Parvovirus, Ehrlichiosis, and more. Trust us for accurate results. Animal Testing What is Parvovirus and why is early diagnosis essential? Canine Parvovirus (CPV) is a highly contagious pathogen primarily affecting dogs. This virus can also infect other mammals including cats. If untreated, the risk of death may be high. Thus, a rapid and early diagnosis could save their lives. Detection of the virus can help you select an appropriate treatment regimen for your animals, prevent the spread of the virus and save them from secondary infections. Why we recommend a PCR test over an ELISA test The sensitivity of an ELISA test depends on the Ag/Ab concentration and the availability. Thus, it could lead to false positive or negative results. In contrast, our PCR (Polymerase Chain Reaction) test detects the viral genome and produces no false positive or negative results. This is because it is dependent on the availability of the virus but not its products or Abs. The positive result of an ELISA test can be caused by organisms other than the target. On the other hand, our PCR test detects genetic sequences unique to the target pathogen. Therefore, its specificity is much higher than an ELISA test. The accuracy of the ELISA test varies, and it depends on the Ag/Ab availability. Our PCR test offers a consistent accuracy of 99%. What is tick fever and why may early detection be crucial? Tick fever is a common canine disease in Sri Lanka which is caused through the bite of an infected tick carrying an insidious and deadly organism. Scientifically, it is known as Canine Ehrlichiosis and Canine Babesiosis. Early detection may prevent the dog from experiencing severe anemic conditions caused by the disease due to the highly pathogenic nature of it. Furthermore, the specific detection will help choose a suitable treatment regimen for your dog. Why microscopy and antibody tests are not ideal Some stages of the parasite life cycle cannot be observed through the microscope. Therefore, the probability of obtaining false results is high. It takes several days to develop antibodies against a certain infection in the body. Hence, it is difficult to diagnose the infection early. Antibodies may be present in the body even after the disease is cured. Thus, if the test is done after the infection is cured, the result may be false positive. What we offer We are the first firm to provide a PCR based animal disease testing service in Sri Lanka. We offer tests which detect Canine Parvovirus, Canine Distemper, Canine Babesiosis and Canine Ehrlichiosis. In addition to animal disease testing, we provide a cattle parentage testing service through the use of DNA typing. Contact us View price list

Accurate Bird DNA Sexing for breeders, pet owners, and conservationists. Non-invasive, 99.9% accurate testing with quick, reliable results. Submit your sample today! Bird DNA Sexing Why DNA Sexing Matters Accurate sex determination is essential for breeding, conservation, and pet ownership, particularly in monomorphic species where males and females appear identical. Even in species with visible differences between males and females, gender traits often develop only in adulthood. Knowing a bird’s sex is crucial for forming proper breeding pairs, helping breeders, and providing important information to pet owners and buyers before selling birds. Sample Collection Process To submit a sample for Bird DNA Sexing, follow these steps: Pluck 5-6 feathers from the bird’s chest area. Place the feathers in an envelope or a plastic zip-lock bag. Label the envelope or zip-lock bag with your bird ID (such as the bird’s name, ring number, or cage number). Complete the sample acceptance form and submit it along with the samples (available at the Genetech Reception or downloadable here ). You can submit the samples in person or by courier to: Genetech 54 Kitulwatte Road, Colombo 00800 For mail or courier submissions, place the sealed samples and completed sample acceptance form inside an envelope. We will notify you once the samples have been received. What we offer We provide 99.9% accurate molecular sexing for a wide range of bird species. Our method is non-invasive, typically using feathers, though blood and other tissues are also accepted. The process is quick, efficient, and cost-effective, delivering reliable results for bird owners, breeders, and conservationists. Contact us View Price List Sample Acceptance Sheet
