Technical Behavioral
I went through several interview rounds for a Data Scientist role and was initially told the process would end after the third round. After that interview I was unexpectedly contacted about scheduling an additional in-person interview, but after providing my availability I never received any follow-up. Multiple attempts to get clarification from the recruiter went unanswered. The interviewers themselves were reasonable and the questions were average difficulty, but the coordination and communication from recruiting were extremely poor. Ghosting candidates after several rounds of interviews is unprofessional and shows a lack of respect for candidates’ time.

So I applied with my CV and cover letter, and then they sent me this coding test on HackerRank. It had 2 tasks and I only had an hour to do it. After that, a while later, they invited me to do this HireVue thing. It was online and I had to record myself answering 2 quick questions. Then they invited me for the Superday.
