Summary

I cleared all interview rounds for an SDE-2 role at Magicpin, including DSA, OOPS, and a system design problem, but the recruiter ghosted me and then rescinded the initial CTC offer.

Full Experience

Round 1: 2 DSA question were asked, I was easily able to solve both of them in given time. The level of the question were easy to midium.

Round 2: Some java OOPS concept were asked, Prepare well for java fundamentals. A easy design problem.

Round 2: The panel includes CTO of the company, We had discussion on what is my current role in the comapny and what i do in day to day work. Then he asked me a problem. Problem statement

As Google, you're attacked by massive DDoS attacks everyday. You've identified a vendor who maintains a regularly updated record of known bad IP addresses. They have an interface that returns true or false for any given IP address.
 
How would you integrate a protection layer across google that uses these and blocks any requests coming from these IP addresses?

cleared this round as well.

Conclusion: Recruiter ghosted me. After acing all the rounds they stopped picking up my call. In my initial screening they agreed upon giving me X amount of CTC, but after clearing all the rounds they say, "we can only offer you X-6 lpa BOSS" they are not interested in offering you. So please avoid such companies
