I was contacted by a recruiter via LinkedIn.

To proceed to the interview rounds, you need to clear a Codility round. Once cleared, an interview day will be scheduled, which will consist of multiple rounds. The process will proceed further based on the results of the first two rounds.

Codility round questions:

1. Given 4 digits, count how many valid times can be displayed on a digital clock.
2. Length of the longest switching slice (continuous fragment) in a given array.

Technical interviews:

1st round (60 mins):

• I was asked about my current project and my responsibilities.
• 1 behavioral question: Any crucial client issue which I have worked on and how did I act on it.
• Write right view of a binary tree.
• Search an element in a sorted 2D matrix.

2nd Round (60 mins):

• 1 behavioral question: Most challenging task I have come across.
• Which data structure is suitable for insert, remove, and get random value with O(1) time complexity?
• And a few questions on data structures.
• Write a program for stack implementation with additional functions (push, pop, getMinimum from stack, getMaximum from the given stack).
