I had 2 interviews. First asked to find max perfect subtree in a binery tree, and write a function to find the root of number. Note the case of x<1 Second Interview with team leader, asked 2sum and dycrypt caesar encryption, can be found on leetcode.

2 technical interviews and one HR. very bad experience, after a great technical and HR interview and telling me that they wanted me to join the team and agree on a salary range they stopped for the stupidest reason "someone else signed the contract before you", even though I didn't get a written contract. they gave no real reason that they hired the other person just that he signed first. furthermore, after a week I saw the same opening on their website so I contacted HR about it (after all everything was great the first time) and they simply ghosted me. they wasted a lot of my time for nothing.

It was a screening process for an internship program they offer. The recruiter spoke to me on the phone and said that I fit the requirements, then- first phone interview, home assignment, technical interview, hr interview.
