Run a campus drive you can trust

Assess a full campus batch or a single senior hire on the same platform: real code, real SQL, a live proctoring wall, and an AI first-round interview for everyone who clears the test.

The problem

Where volume technology hiring breaks down

  1. 01

    One drive, a very large batch

    A campus drive puts a whole graduating class through one test window. The platform, the proctors and the evaluation all have to keep up on the day.

  2. 02

    Copied code looks like good code

    Candidates share solutions in group chats and paste answers from AI tools. A passing test case does not tell you who wrote the code.

  3. 03

    First-round interviews eat engineering time

    Every candidate who clears the test needs a conversation, and your engineers are the ones pulled off delivery to hold it.

  4. 04

    Lateral roles need different tests

    A data engineer, a React developer and a support engineer should not get the same question paper, and someone has to write each one.

How it runs

From an open req to a shortlist

  1. 1

    Set the paper

    Pick questions from your library or generate a draft from the job description. Mix coding, SQL, multiple-choice and written questions in one timed test.

  2. 2

    Run the drive

    Invite the batch. Proctors watch candidates on a live wall with chat, while window switches and face-detection events are flagged automatically.

  3. 3

    Check the code

    Code is scored against test cases, and plagiarism comparison shows submissions that match each other side by side.

  4. 4

    Interview the shortlist

    The AI Interviewer holds a structured voice interview with each shortlisted candidate. The recording, transcript and competency scores land on the same scorecard as the test.

FAQ

Common questions

Which programming languages are supported?

Candidates can code in 10 languages, including C, C++, Java, Python and JavaScript, in an in-browser editor with test cases. You choose which languages are allowed for each question.

How do you detect copied code?

Plagiarism comparison shows matching submissions side by side. Alongside that, the integrity record shows window switches, face-detection events and snapshots for each candidate, tied to the question they were on.

Can we run coding contests and hackathons?

Yes. Contests run with their own question sets and a live leaderboard, which works for hiring challenges and for campus engagement events.

How does the AI Interviewer fit with our panel interviews?

It replaces the first screening conversation, not your panel. It follows a question plan you approve, asks follow-up questions based on the candidate’s answers, and gives your panel a transcript and scores to start from.
