Box Software Engineer interview questions

Worst interview ever. Extremely rude and arrogant people. No respect at all for the people they are interviewing. One of the worst onsite ever. Initially there was a phone interview with the hiring manager . He explained the team and the job. After some delay he arranged for a phone technical interview with one of the engineers. The phone interview required collaborative coding (collabedit). 2 Basic Data-structure CS questions. After not receiving a answer for a week i emailed the hiring manager and he said some recruiter will contact me for the next steps. After another week the onsite was scheduled. Went there. Had a series of interviews with extremely rude people and the most weirdest of CS questions. I get the idea of asking CS questions related to the field. Basic Datastructure knowledge i feel is necessary as well but there is a line between asking good reasonable CS data structure questions and something old school and irrelevant( electrical engineering questions like signals ? waves ? ), even bit masking questions(which i solved) but the interviewer wanted a one line answer which had a worse time complexity than the solution i gave. Google interviews are tough but atleast they ask sensible questions and are nice enough to point you in the right direction/give some hint/acknowledge that sometimes there can be a false negative in interviews. The only good thing was probably the food .
