I applied through a recruiter. The process took 1+ week. I interviewed at Amazon (Bengaluru) in Mar 2013
Interview
I was asked to attend an online coding test in InterviewStreet that had 4 questions to be solved in 2hrs. I solved 2 of them and was short-listed for f2f interview next week.
I attended interview 1st Round. The interviewer was very knowledgeable and he asked me algorithm questions. I was unable to answer properly and thus eliminated after the 1st Round.
Great learning experience and would prepare well to get into it in future.
Interview questions [1]
Question 1
How would you efficiently store a million strings in a data structure so that you would give suggestions if a part of word is typed?
For eg: let there be 5 words cat, ball, basket,banana,bench.
If I type b it should suggest me ball,basket,banana,bench
If I type ba it should suggest me ball,basket,banana
If I type ban it should suggest me banana
..........................
You should show how you store the data, how you then retrieve them to give user a proper suggestion and do this efficiently.
It's exactly same as the dictionary app we use.
The other 2 questions were also challenging.
One was some sorting question that I don't remember but it was an easy one and the other was to how would I structure a TreeMap in java assuming that it doesn't exist in the Collections library.
That moment when the interviewer asked about finding indices in an array for a target sum was wild — I had just tackled something identical while prepping on PracHub. The interview included a technical round with another question about designing an in-memory LRU cache and a behavioral question about meeting tight deadlines. After a smooth discussion, I was told I'd received an offer, which I happily accepted. Overall, the process felt pretty straightforward and not overly challenging.

Question 1
Given an array of integers return the indices of two numbers summing to a target
Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round.
The interviews were 50 mins each.
First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long. The 4 interview questions they asked where three medium leetcode questions. And one system design interview question about how to shadow deploy a test software to millions of users.
