Software Engineer Interview

Software Engineer
Los Angeles, CA

I applied through an employee referral and the process took a day - interviewed at AT&T in June 2011.

Interview Details – First HR called and spoke about my background. Then the team lead called a week later and had a 1 hour interview in which he asked several questions some of which I could not answer. He was impolite in general and never heard back from them again. Was a waste of time.

Interview Question – What is the difference between namenode and datanode in Hadoop?   Answer Question

Software Engineer Interview

Software Engineer
Glendale, CA

The process took 3 days - interviewed at AT&T in April 2010.

Interview Details – Spoke with HR rep first. Then spoke with hiring manager. Set up team interview where I met with hiring manager and 4 team members.

They proceeded to ask me the standard software engineer interview questions. Asked me to white board a few basic algorithms. One guy brought his laptop into the interview and never took his eyes off of it, very unprofessional.

They will hire you if you remember how to do sort and partition algorithms that you wouldn't have done since college. They do not like to speak about your current work or projects. They also ask questions that will tell them how your family life is. For example: "Tell me about how or if you are involved in your community", or "Tell me about a time outside of work, where you took a risk." All of those questions were to get me to tell them if I have a family or not.

Interview Question – Can you do a bubble sort for me on the white board?   View Answers (3)

Software Engineer Interview

Software Engineer
Los Angeles, CA

I applied online and the process took a day - interviewed at AT&T in December 2009.

Interview Details – The interview started from HR, the reception area is crowded, the room where interview performed is hot. The interviewers came in one by one, total 5, each took around 40 minutes. Some of them hadn't seen my resume, and let me think they were so busy. The answers to the questions are not about yes or no, it is about good, better or best. The questions were all algorithm-related, not easy to me.

Interview Question – what is the best way to check a number is a perfect number or not?   Answer Question

I applied online and the process took 4 days - interviewed at AT&T in September 2009.

Interview Details – The interview involved questions on what I was working on. It was more of a technical interview and had questions on my willingness to work on new technologies.
