So far had the coding test on HackerRank which was relatively easy. Two coding challenges and then 8 multiple-choice questions I think. The coding tasks are the leet-code level simple problems like counting objects in the input data etc.

It was the first round interview and was a Hacker rank with Easy-med leetcode qs including MCQs and fill in the blanks. 2 coding qs one was easy palindrome check.

Algorithm Round or Optical Illusion Puzzle? Had an "interesting" experience with the so-called algorithm round. Still not sure if they were testing problem-solving skills or just hoping candidates would get lost in the formatting. The highlight was a question on a bitbuddy tree (yep, that's what they called it) disguised in a 2D array format. Looked like a scene from Inception at first glance—layers within layers. Turns out, all it required was a plain old integer division. The challenge was more in deciphering what they were even asking, not solving the problem itself. Would’ve appreciated a bit more clarity on what kind of "algorithm" knowledge they expect. Feels like they were going for clever, but ended up closer to cryptic.
