A few years ago, a recruiter reached out to me in college. Over the years, I've applied a few times and been told no.

This time around, I studied algorithms and data structures for two months before even contacting a recruiter. Once I contacted her, she asked me for a few dates to choose from, and about two weeks later, I had my interview.

The process was simple (if the questions weren't) from beginning to end.

I haven't heard back yet, so the reason I haven't gotten an offer is partly because I'm still waiting.

Due to NDA, I can't give specific questions, but they really ran the gamut. The questions covered:

• Discrete mathematics
• Parsing string input
• Sorting algorithms
• Recursion vs. iteration (which is better in what cases and why)

The best one was where I was asked to create a data structure that does something. What I ended up creating was an important data structure that I didn't even know was a thing.
