Flipkart Interview Experience for SDE Mobile

I have attended the Flipkart – SDE Mobile position interview on 16th April 2020.  There were total five rounds for this position and each round was too challenging.  These rounds were 

1. MC Round   
2. PS Round  
3. Android Tech Round 
4. Design Round  
5. HM Round

However, who has some basic understanding of java, android development and designing , they can easily crack it. The only important thing, I would like to share with all of you is that time management, and the correct approach to solve the problems as is necessary because some time, if we pick up wrong approach to solve the problem it will take much without any effective result.  Do more practice before appearing in any exam like Flipkart. Please follow for more details.

• You will be given a problem statement (real-world or algorithmic) and you will need to provide a solution in the form of pseudo-code.

Expectations:

• Ability to identify problem types and apply conventionally known techniques to solve them.
• Usage of optimal Data Structures for the problem statement
• Good understanding of Time and Space complexity
• Identify edge cases and boundary conditions of the problem
• Ability to test the correctness of a solution

Domain knowledge (Android): The purpose of this round is to understand your knowledge and understanding of Android.

Expectations:

1. Ability to design and plan a product/feature independently
2. Prioritisation of features/tasks
3. System design and architecture for this product’s implementation
