Initially, the recruiter contacted me and scheduled a 30-minute phone screen. He asked me about my background and resume, noted down everything I said, and informed me that he would pass these details on to all hiring managers.

After a few days, I was scheduled for two technical phone screens on the same day, one hour each.

I was asked basic algorithm questions in both interviews.

I solved the algorithm asked in the first interview within 20 minutes. However, the interviewer kept asking for other possible solutions. He accepted my initial solution as the best approach but still wanted me to identify other methods. I would have suggested 5 or 6 approaches. He then asked the second question with only 5 minutes remaining.

The interviewer in the second call was in a high position but hardly knew how to conduct an interview. She could not answer a simple question I asked her regarding the development methodologies the team used.

I received a rejection email within 3 days after the interviews.

1. Implement a function that accepts two strings and checks if one string is an anagram of the other.

2. Given an array (list) of integers, write a function that determines if the elements can be divided into two parts, each giving the same sum.

3. Email address drop-down application. For example, when typing an email address while composing an email, a drop-down of suggested email address options starting with the same letter(s) appears. Write code to implement this (this is essentially the implementation of a trie data structure).
