Company 1 wanted me for a remote position, but wanted to pay me about half my market rate. This is a casualty of the salary dance -- everyone is so busy hiding their numbers that sometimes you get too far into the process before you realize there's no way to make the numbers line up. If they'd listed a salary range on the original post, or I'd given a salary range in the initial contact, it would have saved everyone time.
Company 2 brought me in for an interview, then went silent for a month, then re-contacted me to resume the process after I'd already taken another job. They're a small security startup, and were really busy due to a security emergency that flared up while I was interviewing, and I slipped through the cracks. Understandable in that case, I guess, but good engineers are rarely on the job market for long, and if you're not able to focus, you will have a hard time hiring them. (Unforgivable in a larger company that has full-time recruiters and HR people, which doesn't mean it doesn't happen all the time.)
