Qless Software Engineer interview questions

Three rounds of phone call interviews. First one is with the HR person who will advise you that this is a start up operation and advises you of the risks. This conversation will last about 30 minutes. Second interview is with one of the developers who will ask specific technical questions about java (what's the difference between and array and hashset or why use a link list). The second interview lasts about 45 minutes. Final interview is with the director of development who will invite you to share a screen and write a program - I was asked to calculate the angle between clock hands at any time of the day or night. This conversation will last about 2 hours.
