Oof. This was one of the worst interview experiences I've ever had. All in all, took over two months to go through their process due to multiple lulls on their side before finally receiving a written offer that I had to accept by the end of the day. I received a tentative verbal offer in early March while they were checking my references. All of my references left great feedback and we moved towards a verbal offer. I wanted to negotiate a starting bonus and the recruiter let me know that he would try his best. A week passed (first red flag) before the recruiter let me know that they actually decided to reduce the offer by 15K (second red flag). The VP of Engineering called me and told me how lucky I was that he was contacting me since I'd never get a similar opportunity to talk to an exec in Big Tech (third red flag; I had already worked in Big Tech before and was recruiting specifically with start-ups). After this conversation, I was still interested to see where the process would go. Another week passed (fourth red flag) before I finally got the written offer and was told that I had to sign by the end of the day (fifth red flag). All in all, would not recommend anyone to go through this long and terrible process!!
