Got a voicemail from the founder in June asking for an interview later in the afternoon, but I did not see the voicemail until at night. Called back & left voicemail next day and the founder texted back saying he will be free in a few hours to call back. The interview was mostly about my previous intern experience. He was very interested in my fluency in two languages, which would be useful in dealing with biotech partners and customers in Europe and Asia. All in all, the interview was easy and laid back.
