I was asked to complete an online assessment three times before having an in-person interview. The laboratory managers were quite nice, but the HR team was really rude and unprofessional.

First round is phone interview where HR calls. Some basic questions are asked, for example: your previous experience, any gaps in employment, why do you want this job.etc The next round is with the hiring manager and director. More knowledge based questions like familarity with certain panels tested (eg. Liver panel, renal panel, lipid panel) instrument principles and other related topics will be asked. Questions about what you can bring to the table, your previous experience that is applicable to the position you're applying for, and any questions with regards to your resume will also be covered here.
