Real-OA question bank in India

Latest verified questions, refreshed daily

Companies covered, every hiring cycle
All your placement prep, right where your students are.
Built around your recruiters
Not generic LeetCode prep — OA Helper studies which companies visit your campus and curates the exact questions, patterns, and timings recruiters use this season.
One platform, every drive
Question bank, mock OAs, branded student portal, and live TPO analytics — one workflow for the entire placement season. No stitching tools together.
Fresh every hiring cycle
The OA changes every drive. So does our bank. Real students share the questions they saw, and we verify and publish them within hours.
Made for placement teams
Single sign-on for your students, granular TPO controls, and full data ownership. Your placement cell stays in charge — we handle the rest.
The problem
Students are losing placements at Round 1 — before their actual interviews.
2026's OA looks nothing like 2018's. Generic prep is failing the filter. The mismatch isn't ability — it's preparation.
Student Reality
Practising the wrong material, every season.
- 1,500 generic questions when 300 targeted ones are needed.
- Practising on OA formats that are 2+ years outdated.
- Never seen the actual style, timing, or pattern used today.
TPO Reality
No way to know who is actually ready.
- No centralised, reliable, company-specific OA source.
- No way to know which students are placement-ready.
- No mock OA infrastructure built for campuses.
Result: 60–80% of students are eliminated at the OA round — before any human ever evaluates them.
What we solve
Questions every placement team asks us.
Common questions we hear from placement teams before getting started.
Question 01
How is this different from LeetCode or HackerRank?
Those platforms are built for individuals practising broadly. OA Helper is built for placement-ready campuses — we track exactly which companies visit your college, curate the real OA questions, patterns and timings each recruiter uses today, and remove the noise so students focus on what matters.
Question 02
We already run mock drives — why use OA Helper?
We design and execute three full pre-placement tests for you, modelled on the companies that actually visit your campus. Your TPO team receives the readiness data per student and per batch; we handle question authoring, proctoring and reporting end-to-end.
Question 03
How do you keep the question bank fresh?
Every hiring cycle, students share what they saw in the latest OAs. Our team verifies the questions, publishes solutions within hours, and pushes updates to your portal daily. Your students never end up practising on outdated material from 2+ years ago.
Question 04
How do we know which students are placement-ready?
The live TPO dashboard shows readiness scores per student, per batch and per company. You can identify at-risk students weeks before recruiters arrive, target the exact weak topics, and run focused interventions backed by data — not guesswork.
Question 05
How is the platform branded for our college?
You get a co-branded portal hosted at your own URL, accessible only to verified students of your campus. Your college identity sits at the front; our infrastructure runs quietly behind it. Onboarding takes five business days end-to-end.
Question 06
What about data ownership and student privacy?
Your data stays yours. We support SSO, role-based access for TPO staff, and clean exports any time. We never share student data outside your campus, and you can offboard with a full backup at any point in the contract.
More questions
Quick answers
+How soon will questions for a specific company be available after we request them?
If our community has covered that company in the current hiring cycle, you will see questions on the portal instantly. For everything else, our team sources and verifies a fresh set within one working day of your request and pushes it directly to your branded portal.
+Can we get college-specific question sets — e.g. Amazon at NIT Jamshedpur on 5 May?
Yes. Every contributed question is tagged with the company, the college, the drive date, and the role. You can filter the bank by all four, so the TPO can pull the exact set Amazon asked at NIT Jamshedpur on 5 May. The dashboard exposes that filter directly.
+Is OA Helper only for tech roles, or does it cover core, analytics and other domains?
Tech-heavy roles (SDE, data, analytics, quant, product) are covered end-to-end today. Core, consulting, ops, and analytics-only OAs are partially covered through community contributions. We scale coverage for any specific recruiter your campus hosts during onboarding — just share the visiting list.
+Is the ₹999 pricing per student or for the whole batch?
₹999 is per student for 12 months. That single price covers question-bank access, the branded portal, three pre-placement tests run by us, and full TPO dashboard visibility. There are no extra platform fees and no per-feature add-ons.
+How are these questions obtained — isn't it illegal to use phones during a live OA?
We never ask anyone to capture questions during a live OA. Students contribute after their drive ends, from memory or rough notes, the same way post-OA discussion forums work. Every submission is reviewed by our team, and the platform terms explicitly forbid recording during proctored assessments.
+Are the pre-placement mock OAs proctored?
Yes. Webcam monitoring, screen-lock, copy-paste lock, and tab-switch detection are on by default. The TPO can adjust proctoring strictness per test and review flagged sessions with timestamped evidence afterwards.
+What does your network look like across other colleges?
We are already live at NIT Rourkela, NIT Jamshedpur, NIT Durgapur, DTU, and NIT Hamirpur, with active student contributors at 40+ tier-1 and tier-2 campuses. Every drive at any campus on the network adds to your bank — that is the network effect of joining.
+How is the OA Helper TPO portal different from our college's own TPO portal?
Your college portal is built for registrations and shortlisting. Ours is built for readiness — per-student practice volume, accuracy, mock-test scores, weak topics, at-risk flags, all visualised by batch and by visiting company. The two complement each other; we are not trying to replace your placement workflow.
+Can we export the TPO dashboard data as CSV?
Yes. Every dashboard view has a one-click CSV export — at the student, batch, and company level. We can also set up scheduled email digests (weekly or monthly) for senior placement staff so the data lands in your inbox without anyone logging in.
+Are there any other incentives for the TPO office in this partnership?
Beyond the platform: dedicated NxtWave onboarding support, priority access to the NxtWave hiring-partner network, a public co-branded "OA Helper × your college" page that improves campus visibility to recruiters, and a free yearly placement-readiness report tailored to your institution.
Loved by India's top campuses.
“Before OA Helper, our students would spend weeks practising on the wrong material. Now they walk into every drive prepared for the exact pattern that company uses. We have seen a clear jump in first-attempt clearances across batches.”
Training & Placement Officer
NIT Rourkela
“For the first time we can actually see how ready each student is, batch by batch, before the placement season even begins. The dashboard gives us a clear picture so we can run focused interventions where they matter most.”
Placement Cell
NIT Jamshedpur
“The questions on the platform are extremely close to what students actually face in real OAs. The freshness of the bank is what stands out — every cycle we see new questions added that match what companies are asking right now.”
Senior TPO
NIT Durgapur
“Our students used to feel overwhelmed by the sheer number of generic problems on other platforms. With OA Helper they now have a clear, focused set of questions per company, and the confidence going into a drive is visibly higher.”
Faculty Coordinator
NIT Jamshedpur
“The setup was simple and the team handled the mock OAs end to end for us. Our students now ask for OA Helper access on day one — that alone tells us the platform is working. The reports help us plan the rest of the season.”
Training Cell
NIT Hamirpur
“I appeared for Amazon and the OA was almost identical to what I had practised on OA Helper. I cleared it on the first attempt, and many of my batchmates had the same experience. Knowing exactly what to expect makes a huge difference.”
