I applied online and was contacted by a recruiter the next day.

The recruiter was very helpful; she had a lot of information about the position and the interview process. After I spoke with her, she emailed me with many tips and links to help me prepare for the interview.

There was a separate person in charge of scheduling the interview, who sent me the names of my interviewers and links to their LinkedIn profiles beforehand.

I had two interviewers for the one-hour technical phone screen. We spent 10-15 minutes talking about my experience, approximately five minutes on a warm-up coding question, and the rest of the time on a harder coding question.

We had a slight technical mishap, but it was quickly remedied. We ended up going about ten minutes over so that I could ask them some questions.

After the interview, it took two days to receive a decision. I appreciated their promptness in contacting me after I applied, scheduling the interview, and notifying me with the decision.

Even though I did not make it to the next stage of interviews, I felt that their overall attitude was that they wanted to help candidates interview successfully rather than looking for reasons to reject people.

Write a function to calculate the maximum depth of a binary tree.

Calculate the shortest distance between two words in a word list. The word list is given to the constructor and may contain more than one instance of each word. For example:

"the quick brown fox quick jumps"

distance(fox, quick) should return 1. (Indices for fox = (3), quick = (1, 4). The smallest distance is between indices 3 and 4.)
