What Ola asks in the DSA round

Ola leans on graphs and geospatial problems that mirror matching and routing, plus a design round on real-time dispatch and surge pricing.

Across the 24 questions on this page, the weight sits on these patterns:

How to prepare for the Ola interview

  1. 1. Start at the top of the list above. The patterns are ordered by how often Ola uses them, so the first two or three buy you the most coverage per hour.
  2. 2. Solve by pattern, not at random. Doing eight dynamic programming problems in a row is what makes the ninth recognisable in an interview — jumping between topics does not.
  3. 3. Tick problems off as you go so the gaps are visible. The per-pattern counts tell you which Ola topic you have actually covered.
  4. 4. Write the approach before the code. Ola interviews are judged on the reasoning as much as the working solution.
  5. 5. Pair this with the pattern guides when a topic is new, and the system design sheet if the role is senior enough to have that round.
  6. 6. If this is a campus or off-campus drive rather than a lateral move, the placement preparation guide covers the stages around the DSA round — aptitude, core subjects and the HR interview — in the order they actually happen.

Ola interview questions — FAQ

How many DSA questions does Ola ask?

This sheet collects 24 Ola interview questions, grouped into 14 patterns. They are questions reported as actually asked in Ola interviews, and each one carries how recently it was reported so you can practise the current set first.

Which topics should I focus on for a Ola interview?

Dynamic Programming, Breadth-First Search, Linked List come first — the patterns on this page are ordered by how often Ola leans on them, so working top-down spends your time where the interview actually is. The full order is Dynamic Programming, Breadth-First Search, Linked List, Hash Table, Sliding Window, Sorting.

How long does it take to finish the Ola sheet?

At roughly 25 minutes per problem — reading it, solving it and writing the approach down — 24 problems is about 10 hours, or 1 weeks at ten hours a week. Most people do not need all of it: the first two or three patterns cover the majority of what gets asked.

Is this Ola question sheet free?

Yes. Every problem, the pattern grouping and the progress tracking are free and need no account. Progress saves in your browser, and signing in with Google only adds syncing across devices.

Can I track which Ola questions I have solved?

Yes — tick a problem on this page and it stays ticked. The counts per pattern update as you go, so you can see which of Ola's topics you have actually covered rather than guessing.
