I had the same experience that somebody described back in April of 2017 in another review, except that my interview process stretched for ~2.5 months. After submitting my initial application, I had 3 phone calls, the audition, the in-person flowchart test, and 4 panel interviews. Everyone I met with was very friendly, but they drew out the notification process for longer than they had told me and then sent a generic rejection email. I wanted to write back to thank them for the opportunity to interview and to request some feedback on what I was lacking, especially because after my final round interview they told me that they thought I would be a great fit for the position and didn't have any reservations about me as a candidate. Unfortunately, their system blocked me from sending this follow-up email. I really wish they would at least provide some feedback to candidates who have dedicated so much time to the lengthy interview process. I would have marked this as a positive experience if they had handled the rejection differently or if they had notified me within the provided timeline.
