Playtech Java Developer Intern interview questions

Initial feedback after applying was explayining application process: 1) initial tests in some online environment 2) technical interview. Test were some basic sql, string manipulation and a hashmap exercise which all had to be completed during 3 hours, inidividual tasks had time limits but could be opened if you run short on another task. Technical interview was with a senior engineer and a team leader, had to debug existing code, add imports, then find a missing number from an array of natural numbers, interviewers wanted to see the problem solving process and were helpful, eg. Gave me a formula if i asked for it.
