Topics Asked: Operating Systems (deadlocks, RAID), DBMS (SQL vs NoSQL, keys, JOINs, MongoDB), DSA (graph shortest path, strings, hashing)
On-campus SDE interview at BlackRock (VIT, 2024). The technical discussion spanned three areas. Operating systems questions covered deadlocks, RAID and general OS concepts. DBMS questions covered SQL vs NoSQL, foreign keys, primary vs unique keys, finding the second-highest record, JOIN types and MongoDB-related queries. The DSA portion included a graph shortest-path problem and several string problems — printing a string in reverse without built-in functions, in-place swapping, counting ASCII values and replacing with the largest value — along with hashing questions on counting character occurrences and finding the second-largest element.
