Worst experience.

There were supposed to be two questions. After coding the first problem, the interviewer asked me to write test cases, which made sense. After I had covered everything, he was still wanting to cover more and kept going back to my solution to verify it worked. I spent the whole time proving that my solution worked. After that, he gave me a follow-up. I was able to extend my solution.

It was just a three-line change, but he told me it was okay since there was no time left.

I was feeling pretty confident but got rejected.

When I asked for feedback, the recruiter told me, “Overall performance was good, but you could not complete the second part.” When I tried to follow up on this review, I received the reply: “It can be tricky sometimes when you first try this exercise.”

Such a waste of time.

Data Structure problem: Create a Database class. In the constructor, you will be given a table. This table is a NoSQL table. Write methods to support table operations, like findRowMinByColumn(column), etc.
