I had four interviews total, including screening, coding, system design interviews, and a conversation with a staff engineer.

The interviewing process was smooth and pretty much straightforward.

Yet, after sharing a reference declaration form, I was ghosted.

Later attempts to reach the HR manager yielded little to no clarity regarding the status of my application. Every answer claimed the application "is in progress."

It seems they are stockpiling candidates until they find a suitable one, and then they don't even care about canceling unfit applications.

A few low-level C questions, followed by an application design exercise.
