Applied in December online.

Was contacted in January.

Screening interview consisted of quiz questions asked by HR and basic behavioral questions. Questions included:

• Why do you want to work at Yelp?
• What are three adjectives your professor would use to describe you?
• What do you use to search code in Linux?
• Is an SQL inner join a union, intersection, or difference?
• Which is immutable in Python: tuple, linked list, or array?
• What port does HTTP use?

The next round involved basic coding and algorithm questions:

1. Write a function to find the nth Fibonacci number.
2. Optimize your code so that the numbers don't have to be recalculated on consecutive function calls (dynamic programming).
