Terrible interview.
1)They want you to follow textbook terminologies and procedures. They do not care about reality.
2)Three people staring at how you write each single "word" of code. They think that you do not know anything if you miss something.
I personally like to code at my own pace and consult resources as needed. If I miss place something in a SQL statement because I was nervous. That is okay in my book. I will fix it. If I do not recall the exact regex expressions in Python, then I will go consult a resource. They just want memorization of every single thing. They want people to be robots. I really did not enjoy the interview. I personally do not think I would have liked to work with these type of people anyways.
