First interview was with a recruiter (voice only, which I find unusual for a remote-first company) who read the company description as well as the job ad that was posted online word by word as an attempt to explain what the position does. When asked about the Business Unit this position would work for, the recruiter did not know anything about it. Second interview was with a Hiring Manager who passed me to the "Interview challenge", which consists of a mock call with a client and a personal presentation to introduce myself, in front of the HM and two other team members. I prepared for three days for the challenge, reading documentation and preparing presentations. Was given great feedback (in the form of praise, but nothing constructive) during the meeting, and some other general interview questions followed through. Two days later I received a generic rejection template from the recruiter. Further attempts to receive any feedback in order to understand what I could improve (not to question the decision) were not replied. I was a referral which lead me to believe they would at least be more communicative, but the overall experience was very disappointing.
