I just had my first round after the HR call. It was a 45 min video interview through WebEx. Interviewer joined the meeting, we just did our brief introductions for like 2 mins and then quickly jumped into coding on codeshare.io platform.

I got asked a version of https://leetcode.com/problems/count-of-range-sum/
I came up with the Brute Force pretty quickly and struggled to get the optimized solution. I finally came with up the Binary Seach Twice (once for lower bound and once for upper bound) idea but only with the some heavy hints from the interviewer. I don't think they'll be moving forward with my candidacy.

Yeah that's it. I hope it helps somebody.

Good Luck!
