Since the comments have shifted focus to hiring/interviewing:
Make sure that your company's interview process leaves enough time at the end of each interview to allow the candidate to ask questions. Don't assume the candidate is OK with emailing questions later because you only left the candidate 3 minutes to talk. The candidate pledged a day of their life to interview as they are interested in your company. If they leave your company at the end of the day without being able to ask all the questions they have, there's a chance they will never bring them up later.
> there's a chance they will never bring them up later
If by that you mean that they will look for another company instead, then I agree. That's what I always do. I am not explaining anything, I just simply ghost the companies who behave like that. I ALWAYS found a more caring company by doing this.
A lot of companies tend to forget interviews are two-way processes, it's as much about them getting to know you, and you getting to know them.
Especially in tech, where you often need to do take-home test; I've seen so many companies not giving feedback on that test. To the point where it seems irrelevant to even do it.
If I don't get feedback on a technical test, through email or a follow-up interview, it's instantly a red flag. The company didn't respect the time I put into it, and I don't see how it will become any better when actually working there.
Please and thank you. After putting me through 3 phone screens and a technical interview or some "5 hour" (really 10 hour) take-home task, I sure as shit do not want to give you any more of my unpaid labor, even in the form of writing up my questions in an email, after a 5-hour onsite interview.
