Total 14 Questions in 120 mins straightly from HackerRank. It's not much relevant to the job I applied if I'd say. It came with 10 mixed multi-choice Questions with typical cognitive Qs like from middle schools and some basic coding Qs, 4 coding problems. Most Qs were the same as already posted in other discussion boards. For example, one Q was about a father age with some information from son's age and father's life. Another was a physics speed and distance Q. The 4 coding Qs needed to read the API requirements, i.e. what the result format it needed?
