Google SE Intern interview questions

First I received an email from HR, informing me to prepare for a telephone interview; Then after about 1 week the interview came: the whole process included 4 parts, each about 30 minutes; The first two parts were relatively simple, some basic questions about Binary Tree; Then came 2 programming questions: just plain recursive code will solve them; The last interview wanted me to improve one of my solutions and I failed eventually.

- Sent my resume through the Google website, for an internship position - After a few days I received a phone call, asking me if I was interested in an interview by phone...I reply "Yes" with enthusiasm - We agreed to a date and time for a phone interview, where I was askied basic questions about Linux System Administration After this...silence for 2 months. I kept sending e-mails asking for an update, they replied politely but still no final answer. After 2 months the final answer..."Sorry, but we decided to take somebody else". In the end they ruined my career, because when I received the first phone call from the recruiter, I turned down a secure offer for an internship with Sun Microsystem. My fault, but partially also their fault...I expected them to be fairer and more professional.
