Candidates describe an Intl FCStone Software Engineer interview built on fundamentals rather than company-specific puzzles. One candidate reports two technical rounds with HackerRank-style data structure and algorithm problems at medium difficulty. That candidate was also asked how they would improve database performance, which felt like an open-ended design discussion. A short behavioral conversation of about fifteen minutes followed.
A separate trainee-level candidate from 2024 describes a different shape. It opened with a two-hour online assessment of 60 questions covering computer networks, RDBMS, SQL and aptitude. A campus technical interview followed. It stayed close to the resume, with a deep dive into one listed project. It also covered data structures, algorithms, SQL, Java, Python, OOP principles, ACID properties, memory management across Python, C++ and Java, and the differences between tuples, lists, sets and dictionaries. That candidate did not receive an offer.
The two accounts differ in format, so prepare for both. Practice timed coding problems, review core SQL, and be able to explain ACID and basic database performance tuning. Know every project on your resume well enough to explain your decisions.
One candidate also reports having to chase HR for updates after each round, with a wait of almost three days for hiring manager feedback. If you are in that position, following up politely is reasonable.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report different formats. One describes technical rounds built around HackerRank-style data structure and algorithm problems at medium difficulty. Another describes a two-hour, 60-question online assessment covering networks, RDBMS, SQL and aptitude. Prepare for both.
Candidates report technical conversations that mix standard computer science fundamentals with resume discussion. Topics mentioned include data structures, algorithms, SQL, Java, Python, OOP, ACID properties and memory management. One candidate was asked how to improve database performance, and another was asked to go deep on a listed project. Expect to explain your reasoning, not just give answers.
One candidate reports a behavioral discussion of about fifteen minutes about personality fit and past experience, which they found straightforward. The same candidate says HR did not proactively update them and that feedback took almost three days after they followed up. Candidates may want to ask about next steps at the end of each round.
