Applied online and received an invite to interview within 2 weeks. First interview was just an initial screening, asking about my CV, some basic questions of my understanding of data science and they spent most of the time just telling me about the company. Received an invite for 2nd interview within 2 weeks. This was full day virtual assessment centre style interview (lasted 6/7 hours). Had to do a programming exercise, give a presentation, talk with HR and an Analytics session. Although it was very long, I actually really enjoyed it and felt like it gave me the best chance to showcase my skills. Everyone who I spoke to throughout the day was really nice and seemed genuinely interested in my work. Best interview experience I've had. Unfortunately my favourable view of the company fell after this point. Took them much longer than they had said to hear the outcome of the interview. Was disappointed I didn't get the job considering how long I'd spent preparing for the interview, but that's okay I spent 7 hours being throughly assessed by them so surely i'll be able to get some constructive feedback? After many emails, and weeks later I still haven't had any. I felt they put a lot of time into me and I definitely put a lot of time into them, as a graduate finding a job is hard enough and any feedback would've been greatly appreciated to take forward into other interviews. I realise companies aren't required to give you feedback but I've had feedback from much shorter interviews, its just so frustrating after all the work I put in and the positive experience I had up until this point.
