Experience:

This candidate, with 2.5 years of experience from a service-based company, received an interview opportunity through a referral for an SDE2 role in Bangalore.

• Round 1 (DSA Round): Although termed a DSA round, it encompassed a wider range of technical topics. The candidate was asked to design a Blocking Queue. Two specific DSA questions were: "Given an array return square of all the numbers" (noted as a LeetCode easy problem) and "Sort 0's, 1's, 2's". The interviewer emphasized the need for optimal approaches. Additionally, basic concepts of Java, Multithreading, OOPS (Object-Oriented Programming System), and SOLID Principles were covered. The interviewer also delved into the candidate's projects and design concepts.

The candidate felt they were not adequately prepared for the deep dives into projects, design, and multithreading. The feedback received was to work on a deeper understanding of these topics at their experience level.
