I applied online. I interviewed at Amazon in Feb 2015
Interview
Pretty fun initial online test with two coding questions and then a bunch of more logic based IQ questions. Both portions had a time limit. For the coding portion of the test you had to write compilable code to properly output the expected results. The questions very fairly simple bit manipulation and data structures.
Interview questions [1]
Question 1
Counting the number of 1 bits in the binary representation of a given integer.
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.

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.
