No matter if you have 1, 2, or 5 years of experience.

Truth is:

If you are giving an interview at any good product-based company or MNCs, 3-5 rounds are just:
- DSA, Development (2 to 3 rounds), and
- System Design (1 to 2 rounds)

No matter what others say, that's my experience: we have to excel in these three areas (DSA, Development, and System Design, including LLD and HLD) to clear any interview; there are no shortcuts.
The playlist below will help you in your preparation:
