The hiring process started positively but completely went off the rails starting from the day of the interview.

One scheduled interview did not happen. The recruiter told me they would contact me again but never did. They never even got back to me with the final outcome and completely ghosted me.

The engineers are not trained well in interviewing. Instead of evaluating a candidate based on their skills and experience, they are more interested in whether candidates can answer a question that fits a template the interviewers have already determined.

Implement a variation of heap sort.
