Sirius CDW Interview Experience for Developer 2023

Sirius CDW conducted the on-campus drive in our college. It started with the pre-placement talk in which they told us about their organization, the technology Sirius CDW works on, their hiring process, and their exam pattern.
It was one of the best pre-placement talks I have ever heard of now.

There were a total of 4 rounds of interview

700 people appeared for the 1st round,

Out of which 50 people make it into the next round, I was one among the 50.

Round 2-(PROGRAMMING TEST)

The 2nd round is completely programming, the candidates are allowed to choose any programming language.

There were a total of 3 programming questions.

For the 1st problem I have written 3 approaches, I have also mentioned when to use which approach, for example when size of array is sort use 1st approach, if the input size is more than 10^4 use the third approach

My pythonic brain wrote one approach which is just one line of solution.
