<human>: Yesterday I had my phone interview for an IT position in a non-profit. I made the cut of 8 out of 125 possible applicants. According to the interviewer I seemed like the best candidate for the position judging from my resume. 

Now I was the first one to reply to his email yesterday within 3 mins. (I get emails to my phone) He noticed that. I was also immediately available for phone interview. So we seemed to hit it off. He didn't ask as many technical questions as I thought he should have. When it came time for me to tell him why I was the best candidate for the job. I feel like I kinda stumbled on that question which should have been one of the easier ones. I also had no questions for him about the position. Normally I'm a firm believer of asking the employer questions. But again, I stumble on that one. So I'm wondering now should I send an email? I would like to make a significant impression. If so, how would you go about it?

<bot>: I had a phone interview yesterday. It could have went better. Should I send a follow up / thank you email?
