3 hours long. Review pre-existing codebase explain what it does what’s good what’s bad, write new feature within the codebase and explain, given a feature and explain your technical design for it and then normal interview

I did an hour long test that was video monitored and four interviews. Mostly about secure token protocols and their software and how it works. After the first two I hadn't heard anything. I would email every so many weeks and they would always say they are trying to figure it out. Eventually I did get an email, several weeks after I was told I would, addressed to another person. It could not have been more impersonal if they just wrote "Son, yousa didn't gets the job". I applied again a month later when I saw another job posted. I was apprehensive because of my first experience but this one started better. But at the end of the process, I was told to expect an answer by a date. This date came and went. I checked in after a day and was told no decision had been made. I waited three more days with no contact and suddenly they called me. Hung up. Called me again, I answered and they started explaining how excited they were that they were finally able to fill the position. Unfortunately it was with another candidate, but they were excited about it and they thought I had a great chance but didn't get the job. This was done by a recruiter who was not involved in the process at all. They couldn't provide feedback. I had requested I get emailed either way, so I assumed it was a job offer. And given it was my Birthday, which they would have known, I felt it lacked a significant amount of tact to call when not requested for a job rejection. They said they would keep my name for future openings, I asked them to remove it. After the way they treated me, twice, they don't have a job I would be willing to accept if they just offered it to me.
