A few interviews and a test. The people were generally nice, but then I did not find out the salary (way too low for Boston area) until the end of the process.

I thought the interview process was going well and had been through three rounds of interviews. They told me I would hear the next steps in 3-4 weeks after the last interview, and since then, it's been radio silence. I have made peace that they ghosted me, but I wish they were transparent in their choices and its left a sour taste in my mouth since then.
