d. Input and output validation using status codes
e. API design considerations and error handling for the function

Phone call 2-

Interview Question – Most unexpected- Recruiter was difficult to reach and had about <12hrs warning before scheduling interview. The actual interviews went well- the engineers were easy to talk to and walked through the problem solving.   Answer Question

## Software Development Engineer Intern Interview (Positive Experience; Easy Interview)

I applied through college or university and the process took 5 days - interviewed at Amazon.com.

Interview Details They attended a local career fair at my university - I handed them my resume and was asked to apply online with a certain code for SDE Interns. I applied and received a call scheduled for the next following day to interview. Interviewed, and got the email offer within 4 days.

Interview Question – Very typical codeable question for an undergrad - something you would get from cracking the coding interview. Only one question was asked - I then chatted with both interviewers for 45 minutes each separately for two back-to-back interviews.   Answer Question

## Intern Interview (Neutral Experience; Average Interview)

I applied online and the process took 4+ weeks - interviewed at Amazon.com.

Interview Details After submitting my resume, I received an e-mail from their recruiter inviting me to an interview. They were doing interviews at my university on specific days, so I was asked to choose one of those days and specify a time slot that works for me.

At the interview, there were two Amazon engineers in separate rooms and I had to do a 30-minute one-on-one interview with each of them. They weren't notably friendly, but both were very polite and respectful. The interview consisted mostly of technical programming questions - there were probably only 2 or 3 general questions.

Interview Question – You have a file with 4 billion integers. Find an integer that doesn't exist in the file, given that you have very little available memory on your computer.   View Answers (5)

## Software Development Engineer Intern Interview (Positive Experience; Average Interview)

I applied through college or university and the process took 1 week - interviewed at Amazon.com in February 2014.

Interview Details Applied online in January and after 2 month when Amazon hosted a career fair on our campus, got selected for back to back 90 mins interview. 45 mins with each interviewer. Questions are standard questions. If you do problems on UVA online judge, Topcoder or Hackerrank regularly, these type of interview questions should be fairly straightforward to answer.

Also, as many other big tech companies, just solving the problem is not enough. It's also important that you make sure your thought can be understood by others. Explaining how you come up with a solution with clarity is much more important that just solving all of the problems without saying how you did it.

There are four questions. 1 focus on math, 1 on building trees, 1 on linkedlist and 1 on string manipulation
As always, make sure you also understand the complexity and performance of you solution.

Negotiation Details – No negotiation. But I think the final offer (final salary) also depends on your performance during the interview.
