Software Development Engineer 1

Candidates typically face three rounds: a technical coding round focusing on data structures and SQL, a system design/technical deep dive that tests knowledge of data pipelines and cloud architecture, and an HR round. The difficulty is moderate, with an emphasis on practical problem solving and data‑engineering concepts. Preparation should include coding practice, SQL queries, and understanding of ELT workflows.

Round 1: Technical coding (data structures, algorithms, SQL) → Round 2: System design and technical deep dive → Round 3: HR interview
