The same old strategy... Linkedin contact, recruiter call, phone/coderpad interview... Later got an email rejecting. I got say, the guy that was interviewing was very junior, he even said that was his first job and he was there for 2 months and he is the one assessing new engineers. Well, I guess I didn't make the cut, but the fact that my code was the best solution for the question, they still rejected. I suspect the interviewer didn't know much about binary trees , more also, he was very confused when I asked him that my code will handle the cases where unbalanced binary trees are presented, which he said he wasn't aware of such type of "data structure" ...LOL what a joke.
