1. Create a linked list and write the functions to add, delete a node. 2. Count how many ones in an integer number. 3. Reverse bits for an integer number.
HM Call - 1. To understand past projects, scale, high level knowledge, etc. 2. Pretty straightforward. Machine Coding Round - 1. Did not involve any technical questions. 2. They seem to just ask simple questions around abstractions, code extendability, etc. 3. Few subjective questions on different scenarios such as using a cache, security tool, etc. HLD Round - 1. I was told this would be a HLD round but turned out to be a machine coding round. 2. Design a inmemory ledger kind of a system that can debit, credit amount. Add extensions with interface / abstraction for reserve balance, etc.
=== TECHNICAL === • I was asked to implement JSON.Stringify. (ehem, ehem, creativity and novelty in the problem to ask!) • I finish that with unit tests in half an hour which later I found was working way better than all the version I could find online in random people's public github accounts. • The interviewer asked me to support recursive loops in Javascript. He didn't even have a working example and it was super-tricky to think about it -- an object having properties to point to the object itself to form a loop of "pointers" in Javascript! I modified my code to cover that too. I tested that and it worked perfect. • And guess what, the feedback (more than a week later) was that there are "some concerns about my Javascript" so they need to have a second phone interview. lol. I could only laugh! I just bailed out and canceled it. Enough is enough.
