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.

Discover Genetech’s specialized testing services: from pioneering molecular diagnostics and DNA typing in Sri Lanka to precise GM food and animal disease testing. Ensure accuracy with our PCR-based tests. Our Tests Molecular Diagnostics We pioneered the use of molecular diagnostics in Sri Lanka. We seek evidence of a disease at the basic causative level by detecting the nucleic acids based on PCR technology. Read More GM and Other Food Testing We use a PCR method to identify the most common genetic elements that are generally found in Genetically Modified (GM) crops. Our test can be applied to a wide range of food items including crops and processed food. Read More DNA Typing We pioneered the use of DNA typing for human identification for forensic casework and analysis of family relationships including parentage testing. Read More Sex Determination of Birds Many bird species are monomorphic; thus, males and females cannot be distinguished visually. We offer molecular sexing for proper gender assignment of a wide range of bird species with an accuracy of 99.9%. Read More Animal Testing We are the only 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. Read More

Learn about Psittacine Beak and Feather Disease (PBFD) and how Genetech offers a PCR-based test for early detection. Submit feather or blood samples for reliable PBFD screening. Psittacine Beak and Feather Disease (PBFD) What is PBFD? Psittacine Beak and Feather Disease (PBFD) is a viral infection caused by a circovirus, primarily affecting parrots, cockatoos, and other psittacine birds. This virus leads to feather abnormalities and changes in beak formation. PBFD spreads through feather dust, faeces, and contaminated surfaces. The infection can be deadly in young birds and, in some cases, adult birds, as they may carry the virus without showing symptoms. As there is no specific treatment for PBFD, early detection is crucial for effective management through stringent quarantine and hygiene practices. Sample Collection Process To submit a sample for PBFD screening, 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 (name, ring number, cage number, or other preferred identification). 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 At Genetech, we offer a PCR-based screening test for PBFD using feather or blood samples.

Discover GRI’s commitment to high ethical and legal standards in scientific research. Learn about our rigorous guidelines for human subjects, bio-hazardous agents, and international compliance. Legal & Ethical Guidelines GRI will conform with all existing Laws of Sri Lanka regarding the performance of scientific research. Where such Laws do not exist, we will seek guidance from regional and international Laws. GRI will act as a responsible scientific entity, and will maintain high ethical and legal standards at every stage of the research project. We will require the following from all external researchers: All projects involving human subjects or human specimens will be evaluated by a GRI institutional review board (IRB). Human subject research requires the approval of the GRI IRB as well as the IRB of the investigators' home institution. A written guarantee of the source, the collection methodology of the tested material and the end use of the data is required. For samples with restricted access such as protected or endangered species, the external researcher has to provide copies of permits or permission from relevant authorities. GRI retains the right to verify the legal and ethical status of any tested material, in consultation with relevant authorities or experts. GRI retains the right to terminate the research project at any time if it is discovered that that the tested material was obtained illegally or unethically. GRI will not be held responsible for any observations and conclusions made from such research, or for any subsequent action taken by any person in response to such observations and conclusions (except when the research is performed in collaboration with a senior scientist at GRI). Projects involving work with bio-hazardous agents will be reviewed and only undertaken if the specimens do not pose a significant risk to people working on the project or others. Only international shipments that are compliant with local and foreign import/export regulations will be allowed.
