Interview questions [1]
Question 1
Case interview was tough - Business had 2 products, one with positive and other with negative revenue. Proposed new ways to do business for negative revenue product, such as corporate B2B deal. Asked to make graph and recommendations
The whole process took about two and a half months, and honestly was over the top. Firstly an online code test which was essentially Excel filtering and SQL. Secondly I then had to complete a coding challenge which they said took about 8-10 hours (with the classic line of "but some people like to do more"). I finished it in about 30 hours. Finally there was four interviews of which two were case studies, a code review (that requires a PowerPoint about your analysis) and then a "tell me about a time when" interview. After following this process I was promptly met with a rejection email and no feedback. Overall the people I met were nice but the amount of work involved to prepare for each stage made me worried about how inclusive the company might be, I know I couldn't manage these tasks on while working another job if I had children or someone to look after.
