A recruiter contacted me on LinkedIn. I responded with interest, and she scheduled a brief phone screen.

She then emailed me with many helpful links on LinkedIn technologies, coding, and interview tips. The next day, the recruiting coordinator emailed with my technical phone interview details.

I had a phone interview with two senior engineers that involved coding in real-time. The following day, I received word that they would not be further pursuing me as a candidate.

The whole process was quick and pleasant. All the people I spoke with were friendly and respectful.

A user logs in to a website with proper credentials, and the user is taken to a blank page. How would you troubleshoot that?

Coding: Create a stack with the usual push() and pop(), but with an additional function getMiddle() that returns the middle element of the stack in constant time.
