They asked a lot technical questions, all of them were from both the 'essential' and 'desireable' qualities, make sure you check each single technical terms, and what the common assays used for what kinid of applications, how they are different ( not testing your knowledge in the experiment procedure, more like checking if you have any general idea and understand the underline principle). Overall, I think for the technical questions they were trying to understand where my limit was, so they asked a lot. They also asked situational questions (research ethical, data safety, lab safety, and how to deal with the shortage in samples and budget in your research). This part I feel like they were asking my answers to get an idea my personality and my work style in this situation which they needed to deal with daily (a biotech and start up) My suggestions are thinking about some common situation 1) how to deal with financial issue in a start-up in that position you applied 2)how to share a lab with others/ deal with chemical hazard/ multiple cell lines/ lacking of samples/multiple prohect/ availability of the hoods or machines 3) how to keep your data safe / company's property Final part was behaviour questions, like your weakness and strength, why this position/company, how your friends discribe you ect. what kind of working environment you like. Other questions like what business will you invest if you have a lot of money et. From the order of the questions asked, I think they are more curious on how good this candidate in technical skills, then they check if you are a good fit with their working environment. All interviewers are very nice, and they are quite straight-forward ( which I really like). Feels like a working environment you can discuss a problem without being accused/criticised. From the structure of this company ( you can check it from LinkedIn, the past experience & education backdround of the employees), I feel like their leaders know what they want, so they know exactly who they need and where to put them. That also means this company has high standard for candidate selection, and higher potential/ chance to survivial as a start-up, which is not easy. It's a shame I didn't get the job... I quite like them
