First applied through a campus career fair and was contacted by a recruiter who conducted a phone screen. This was followed by a 45-minute Skype technical interview with an engineer about a month later. I did not advance past the first technical interview.

Phone Screen:

The phone screen recycled questions already available on Glassdoor. The recruiter was non-technical and primarily focused on obtaining the correct answer. Typical behavioral questions were asked, followed by knowledge-based questions.

Skype Technical Interview:

The Skype interviewer was helpful and friendly. They provided assistance if you struggled and offered hints to possible solutions without giving away the answer when you were stumped.

Behavioral Questions:

• Why Yelp?
• If you could do anything at Yelp, what would you do?
• Yelp throws a hackathon 3 or 4 times a year (details about the contest provided); what would you submit?
• What is the most difficult project that you've worked on?

Knowledge-Based Questions:

• What's the difference between TCP and UDP?
• What's your favorite programming language? Why?
• What are some disadvantages of that language?
• Explain in detail the steps/processes that occur from the moment you type a URL in a browser and hit enter.

Technical

Given an unsorted array of numbers (that may contain repeated numbers), print or produce a data structure that contains all pairs that sum to a number k. Do not include pairs that are the same numbers in a different order.

Ex. [3,2,6,2,0,5,3,8,7,10] [(0,10),(2,8),(3,7)]
