I applied online. The process took 4 weeks. I interviewed at Numerator (Chicago, IL) in Dec 2021
Interview
The interview process was pretty lengthy, they have you move onto phone interviews w/different levels of people. If you make it far enough in the process, they will give you a case study where you're asked to solve a problem and present back to key interviewers. I went through all stages, presented, and then was ghosted - never heard back from them. It's unfortunate that you'd have someone go through 5-6 rounds of interviews, they can at least send a form email that someone didn't make the cut rather than leave people hanging.
Have to do a presentation for the final stage. Took a few hours to prepare and another two hours to present and interview on. Not too difficult but very time consuming.
The process took 3 weeks. I interviewed at Numerator (New York, NY)
Interview
The interview process was smooth. Very little time between each communication from the recruiter. The first two interviews were informal: each interviewer allowed me to ask questions about the company, the role, etc. for the entirety of each 30 minute call. This was very unorthodox in my experience, but a welcome change of pace.
After the first two interviews, you are given 5 business days to prepare a case study with several data files and a business question to answer. I understand the reasoning behind a case study, but the amount of effort required on top of your 9-5 is overwhelming.
I felt the presentation went ok, but I received a rejection notice the next day. The hiring manager actually followed up with feedback - which is beyond what I expected - but much of it contradicted instructions for the case study. For instance, one instruction was "do not do a full blown analysis, only show one or two examples" and feedback was, after including one or two examples, "we felt you could've included more data." Very frustrating. I almost wish I didn't receive the feedback.
Interview questions [1]
Question 1
What is your process when tackling a business question? (this was asked during the case study presentation, as virtually no questions were asked during the first two interviews)
