1st round interview record the general questions via Hirevue. 2nd round given Challenge B hackerrank questions, it is a coding marathon. Time is limited I didn't finish the coding session. Math problem are relatively easy. 3rd phone tech interview, also about cooooooooding, was asked to finish some lines of code, output of a chunk of code, some questions about garbage collection, data type and oop inherit, polymorphism. And oo design performed in hackerrank. Got rejected in a day after 3rd round, the whole process is about 1 month and half. Feeling exhausted after too many coding challenges. Feel like they didn't filter out people without the expected experience in leetcode in 2nd homework.

Followed by 4 hours of interview on the same say, with technical round(asking about your experiences and 1 LLD question), Manager round(resume again, and behavioral), HR round(basic behavioral)
