I was approached by their staff for an interview. Had a 30 minute phone interview, then 2 office interviews. The 1st office interview was half-technical, the 2nd was all technical. Despite thinking that I had done well, liking their interview process, getting a good impression on their product, and gelling with their culture, I was rejected due to reasons unknown. I tried to contact them afterwards for a reason, but silence. Very disappointing. I had a lot to offer on both the product and engineering side, and was excited to get started on a new platform! Perhaps that excitement translated into nervousness for the 2nd interview? A hiring process with the growing flaws of perfectionism and pedantry.
