I submitted my resume online and was contacted for a phone interview. This was the first time Google actually responded to my application in my four years of college.

The interviewer was super friendly, and the questions were quite reasonable. I've heard many people say they've been asked irrelevant questions by Google engineers, such as asking a Java person about writing garbage collectors using C++. However, that didn't happen to me. The interview questions were very reasonable; they focused on data structures and practical algorithms. The difficulty was average.

After two weeks, I heard back from the recruiter for an onsite interview, and that was the worst part. It took them more than two weeks to find a date for the interview, which was scheduled six weeks after I was informed about the onsite. I understand there are a huge number of people applying to Google, but the long procedure is unreasonable, especially considering there's a team match after the onsite, which could take another couple of months.

Therefore, I went for another opportunity. If it were five years ago, Google might have been worth waiting for. But now, there are many great companies out there, and Google is not the single best option anymore (actually, maybe not even one of the best).

In addition, I told the Google recruiter that I was not going to continue with them, but I still received interview arrangements from their coordinator several days later. Their recruiting system has serious problems.

Given a string of words, find anagrams and group them into lists. Then, output these lists of anagrams.
