Phone screening: a fairly simple tree-traversal question. The interviewer was encouraging and helpful
On-site:
1) Describe a challenge you have encountered at work. The interview was mostly about nothing. The guy who claimed that he worked for more than 10 years for the government behaved like a typical dissatisfied with his position clerk. He never smiled and has not encouraged a dialogue.
2) A back-end engineer asked tried to figure out if I understand how things work on the back-end. The guy for a change was nice and it felt more like a conversion than an interview.
3) An iOS developer asked to implement a simple regular expression parsing algorithm in Swift. The first warning sign was that the guy did not even bother to introduce himself. The second was that he put his legs on the table. Interviewing is hard hard both the interviewer and the person being interviewed; why make it ugly?
As I wrote the code to answer the question the guy suddenly left with the words "Let's finish with good note, your code will probably work." Next a lady arrived and said good luck we don't like you both socially and your write code slowly. Lunch was being served in the dining room but I was not offered to join. I am ok with not being compatible but the whole interview felt ugly.
