“ What separates the programme from similar products out there is that it is hardcore learning-focussed. And the mentor is a priceless addition. My mentor Raghavendra Singh was extremely helpful, setting everyday targets and helping me pay attention to detail.

**2-4 Coding interviews**which focus on basic problem solving and data structures. The less experienced you are, the more the number of coding rounds for you.**1 Design interview**which involve coming up with high level design architectures for real life products as well as OOPS based design of components. This round might be scrapped for you if you are interviewing for an entry level software engineering role.**1 Hiring manager round**which tests for cultural fit based on attitude and previous work experience. In depth knowledge of previous tech used is paramount here.**An optional bar raiser round**which is a combination of all of the above. The idea is here to judge if you are technically better than an average person in a particular Amazon team.

**Coding rounds:**Material in the programming section of InterviewBit is pretty comprehensive. For your reference, the section below has some of the questions which are frequently asked in Amazon's Interview. Make sure to try and solve most of them.**Design rounds:**InterviewBit System Design prep has you covered here. Make sure to go through some frequently asked interview problems listed on the page.**Cultural fit rounds:**In most cases, this should not be an issue. However, go through Cultural Fit Interview Guidelines to make sure you don't make common mistakes.
