Process
Parallel programming was the topic of my two-part interview question. The interview itself was straightforward, but I ended up writing two solutions because my first did not have the best time complexity.
Pros:
- The interviewer was nice and helpful.
Cons:
- They said I would hear back no later than 3 days after the interview, but I never did.
- I even tried following up with my recruiter and never heard back.
Questions
Find differences between two two-dimensional arrays with a solution that has the best time complexity.
