Where to apply

Ask for a referral to JetBrains

A referral only means something if the person giving it can actually speak to your work. I will refer you where I know someone on the inside and your profile genuinely fits the role, and I will tell you plainly when I cannot. Either way you get an answer, and a straight one.

  • I read every request. A reply takes a few days, sometimes longer.
  • I will not refer someone for a role their profile does not fit. It wastes your time and costs me the contact.
  • Where I cannot refer you, I will say why, and point you at the way in that does work.
  • Nothing you send here is shared with anyone without you agreeing to it first.

If you found the opening, paste it. It tells me which team you mean.

A Drive, Dropbox or personal-site link is fine. Make sure it opens without a request for access, or I cannot read it.

At least a short paragraph. This is what I would be putting my name behind, so specifics beat adjectives.

Comma separated, up to six. Things you would be happy to be tested on.

How they hire

The exact interview content depends on the team, and the recruiter explains the focus of each round beforehand.

  1. 1

    Recruiter call

    Official
    Recruiter screen

    A walk through your last two or three roles, your impact and what you want from your next job.

  2. 2

    Team interview

    Official
    Technical interview

    A conversation with one to three team members and the hiring manager that may include live coding, a case study, a code review or a discussion of past projects.

  3. 3

    Take-home task

    Official
    Take-home assignment

    For most roles, a realistic assignment done in your own time and reviewed by potential teammates. Relevant side projects or open-source work may sometimes stand in for it.

  4. 4

    Task review

    Official
    Technical interview

    A discussion with the team about your design decisions, trade-offs, how the solution could evolve and how you used AI tools.

  5. 5

    References

    Official
    Final HR round

    JetBrains contacts referees, ideally former managers and key stakeholders, about collaboration and ownership.

  6. 6
    Offer

    An offer follows when skills, motivation and expectations line up.

What comes up

Recurring themes from candidate accounts, not a question bank. Nobody is served by leaked question lists, least of all you in the interview.

  • Trade-offs and decisions

    Official

    Interviewers want to understand how you think and the reasoning behind decisions in projects you have worked on or led.

  • Following instructions without overengineering

    Official

    For the take-home, JetBrains says the key signal is whether you followed the instructions, and strong candidates avoid overengineering.

  • Algorithms only with notice

    Official

    Recruiters share what each interview covers, and you get advance warning if algorithmic questions are included.

Course
Grokking Algorithm Complexity and Big-O

A short text course on algorithm analysis: all five asymptotic notations, time and space complexity, best, worst and average cases, and three methods for recursive complexity including the master theorem. It suits students and self-taught developers who can write working code but freeze when an interviewer asks for the time and space complexity, or who want to understand why one solution is faster than another.

Course
Grokking Data Structures & Algorithms for Coding Interviews

A foundations course that builds eleven core data structures from the ground up (arrays, matrices, stacks, queues, linked lists, trees and BSTs, hash tables, hash sets, heaps, graphs and tries), then covers sorting, searching, greedy and divide and conquer. Every chapter has practice problems, flashcards and an assessment. It suits students and career switchers whose foundations came from tutorials and who find pattern courses move too fast.

What it pays

Nothing collected for this company yet, and nothing worth guessing at. A made-up range is worse than no range because people negotiate against it.

Add to the JetBrains page

This library is only as good as what people who have been through it are willing to share. Most of these companies have no hiring process documented anywhere, and one account of what the rounds actually were is worth more than anything I can research from the outside.

What are you adding?

This decides how the claim is labelled on the page. Only someone representing the company can produce an “official” label, and I check that separately.

Year and month.

Comma separated topics, not the questions themselves.

Round by round is ideal: what each one was, how long, remote or in person, and what it covered.


Credit

Anonymous is the default. If you keep it anonymous, nothing identifying you reaches the page: it is published as a candidate account and your name stays with me. Never send anything covered by an NDA, and never send a take-home or a question paper.

Universities they recruit from

No sourced university links yet. A campus drive, a career fair appearance or an internship partnership is what puts a university here.

Want me to refer you here?
