The team is such a mess and disorganized at their hiring. First of all, the process is very long and has 6-7 rounds as the recruiter described. Second, the team ghosted you, and the recruiter didn't know what was happening. I have been waiting for almost 1 month since I submitted the take-home assignment (round 3). The next round was supposed to be a review session as we talked. One day the recruiter reached out to me asking for a time schedule to chat with the team. I replied to check if that would be a review session, and then the recruiter immediately responded to withdraw the previous email and declined my application. I didn't even have the chance to review the exercise with the team and got rejected without explaining why. The exercise was not too hard but this was very disrespectful to the candidates.

Was ghosted after the case study. They have had this job listing up for 4+ months and have still not hired anyone. Either they don't know what they're looking for or use applicants for free consulting work. Regardless, it doesn't matter. If you're asking tons of applicants to do tons of hours of free work, you need to at least give a response to why it doesn't work. Do better.
