How do people here feel about feedback for technical tests that take at least a couple of hours? Personally I don't care if I'm not given feedback after a phone interview, or even an on-site interview. But when it comes to technical tests, I would really appreciate feedback, since it could actually help me improve my coding skills, or at least know where I need to improve. If I'm not given feedback on these, it's just another red flag to me, the company doesn't value my time, and seems to treat the interview process as a one way street. I recently was asked to do a coding test, the HR person told me to do it over the weekend, as most candidates needed all the time they can get. I told HR I was only willing to spend around 4 hours on it, they could judge me on whatever I could do in that time. And even working for free for 4 hours was as stretch, after all, I'm not getting paid, there are other things I could've been doing. And to this day they haven't even acknowledged my test, I did get through to the next round, but no mention of my test whatsoever.
