The Turn Lab interview questions

Submitted application through their website. Overall pretty straightforward. Got an email to schedule a phone call about a week after. Replied with a couple of times that could work for me. The only downside was that they were not very responsive after this. They replied about 6 days later with a time that worked for them for phone call. This is fine, just be mindful of applicant's time too. A lot of us already have full time jobs, and it's just polite to give some notice. Never heard back from them after, which of course I assume just wasn't a match. My only concern with this is that if you have someone make time out of their schedule to have a 30 minute call with you, the least you could do is send a generic "Thanks, but no thanks" email. I understand not being able to respond to every applicant who submits an application. But when you ask them to make time for you, it's only right. Let's improve the interview process for our generation and those to come.
