How to Prepare for Ola
Ola is coding-first with mobility marketplace flavor later. Clear OA before polishing domain stories.
What Ola actually tests
First round: Ola OA + interviews
Time split that matches how candidates report outcomes (not a marketing pie chart):
- DSA 45%
- Projects 25%
- Culture 20%
- Mocks 10%
Patterns are from student reports and vary by role and drive. Trust your college placement email over blog folklore.
Hiring flow you should prep for
| Stage | Time | What they check |
|---|---|---|
| OA | timed | DSA |
| Tech + HR | multiple | Coding + ownership |
Time allocation
- Understand eligibility criteria (6.5+ CGPA, no backlogs)
- Study exam pattern (OA with DSA problems, technical interviews, system design)
- Practice previous year Ola placement papers with solutions
- Master DSA fundamentals (arrays, trees, graphs, DP) - solve 100+ problems on LeetCode/HackerRank
- Learn system design basics (ride matching, payment systems, scalability)
- Prepare for technical interviews (coding, algorithms, projects)
Daily loop (75-120 minutes)
- One timed block that matches Ola’s first round (coding + culture)
- Log misses: topic + why you failed (speed, concept, carelessness)
- Re-solve yesterday’s misses cold
- Twice a week: 10 minutes of resume/project narration out loud
6-8 week startup plan
| Week | Focus | Exit criteria |
|---|---|---|
| 1-2 | DSA fundamentals | Clean easy/medium solves |
| 3-4 | Projects + ownership stories | Resume bullets measurable |
| 5-6 | Mocks + culture | Explain trade-offs under pressure |
| 7-8 | Weak topics + HR | No unfinished ‘hero’ projects on resume |
Round-by-round strategy
Online Assessment
- Order problems by confidence after a 3-4 minute skim
- Passing test cases beats a brilliant half-solution
- Invent edge cases before submit; watch timeboxes
Technical interviews
- Restate → brute force → optimize → code → test
- Show ownership; unfinished resume projects get punished.
- Tie CS answers to a project when it strengthens the point
HR / managerial
- Why Ola, why this team/role, location flexibility
- STAR with a metric; pick 2-3 real company values and prepare proof
Ola-specific drills
- Graphs/heaps/hashing
- Dispatch/matching reasoning
Topic checklist
- Working code in one language
- Projects you actually shipped
- Ownership stories
- Product sense lite
- Breadth across stack claimed on resume
- Full-length mock every other day
- Light revision only - no new rabbit holes
- Sleep, ID proofs, machine/network checklist for test day
Final stretch
30 days out: weekly full OA-style mocks; close weak DSA patterns; draft STAR stories.
7 days out: alternate mock / review days; re-solve misses cold; no new patterns.
Day before: skim notes, check machine/network/ID logistics, sleep.
Common mistakes for Ola aspirants
- Weak coding with only ‘mobility domain’ talk - fix this first
- Preparing only interviews while failing Ola’s first round
- Collecting notes without timed mocks
- Listing five frameworks on the resume and defending none
- Changing language/stack one week before the drive
- Listing half-built side projects as production
