Campus OA Problems

Fidelity hires freshers in India mostly through campus and summer-intern drives, and those drives start with a timed online test on HirePro or HackerRank. US and experienced candidates usually go straight to interviews and won't see it. The aptitude and CS multiple-choice sections come first, then two coding problems at easy to medium level, all on one clock of about 90 minutes to two hours. Keep the early sections tight so the code gets most of the time. The free Java Fundamentals & the OA lesson covers the format and works three problems. The three here show more of the shapes the test uses.

Each of them hides a simple count under some setup. One spends a full paragraph on its story before it gets to the rule, so skim for the rule and the return value first. Brute force passes the small cases and times out on the large ones, which means you should work out what to count before you write a loop. Keep any total that can grow in a long.

The set runs from a quick count to a tally with a padding rule that's easy to miss. You can pick your language on the test. Java matches the rest of Fidelity's process, so use it if you're fluent, and use Python if you're faster in it.
