Interview process for a lab tech position is not too difficult. They give a tour of the facility, an introduction to different areas, ask you about team work, background, education, interests, etc. Asking questions to show them interest might help and willing to take on different/multiple roles is a plus. Not a bad place to work for entry level science job to gain experience. Be professional, on time and do research on company and toxicology so you have a basic understanding of what is going on. Overall, interview process is not hard.
