Initial phase was a recruiter reach out to schedule an interview, and typical questions about past case examples using your skillsets. If you're a match, you are given a take home competency/IQ style test that is timed. Pending your results, you are sent to a round to do a case study with an operations manager. Prior to the case study, the recruiter followed up to do a sync prior to the case study, and helped answer questions.
In my experience, everything went alright, although there was some lag and rescheduling associated given it was around the holidays. The case study interview was conducted at about 8:30/9:00pm their time, so it did raise some concern on the interviewer's focus and their WLB. Overall, the feedback to me from the recruiter and interviewer was "exceptional" and the case study went very well. After the case study, I was informed that my case was an actual case, my solutions proposed were used nearly verbatim, and they were very pleased with my answers. I was left a bit confused, as about 36 hours later, I received an automated response saying I was not a match for the role. I asked for actionable feedback only to be ignored, and sent another automated "interview survey".
After thinking about the process, I was pretty divided - the initial recruiter was splendid and super helpful, the second recruiter who coordinated the interviews was nearly useless, and the case study interviewer gave very mixed feedback. To be honest, it seemed like it might have been a phantom role given others' feedback on the role - going through a lengthy process just to be removed without reason. Regardless, I'm sure this isn't an experience I'd recommend going through given the time commitment required versus their effort to assure a smooth process.
