The interview process consisted of 3 rounds.

A prep sheet was sent to prepare for:

• 1 round of Data Structures and Algorithms (DS/algo)
• 1 round of System Design
• 1 round of Behavioral

It seemed unusual to have a System Design round for an entry-level role, but the recruiters confirmed it after I reached out. That round, however, ended up being another DS/algo round where a LeetCode Hard question was asked. When I inquired with my recruiter why I was asked to prepare for System Design, they did not respond and ghosted. The rest of the interview was mostly easy.

This experience highlights inconsistent interview practices and recruiters who do not take accountability for misleading candidates.
