Start organizing your interview questions! (Question history)

Instrument

I don't know how long it's been since I started putting my resume in front of companies in earnest... I think it's been about 3 months, but I'm not passing all the coding tests, but I'm passing quite a few of them, and I've had a few interviews recently!

But even if I go to an interview, even if I have studied CS, there is a difference between the questions that come up in the interview and the CS knowledge I have studied... So I would like to blog about the questions that came up in the interview and what I studied with Pinpoint.
