Where to apply

Ask for a referral to Supercell

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

Supercell does not publish a round-by-round engineering loop, only a general description of how it hires. Most roles are based in Helsinki, London or Shanghai. Remote work depends on the team and the role, and is currently possible from countries with a Supercell office, plus Denmark, Sweden, Germany and Spain.

  1. 1

    Application, reviewed by people

    Official
    Application screen

    Supercell says a person reads every application, with no automatic CV filter. Roles stay open until the right person is found, so there is no fixed closing date, but it recommends applying early. It does not accept open applications.

  2. 2

    Interviews across several teams

    Official
    Panel interview

    Candidates meet many people and are interviewed by several different teams. For roles that need you in the office, Supercell pays for travel and accommodation for onsite interviews, so you also get to see the office and the city.

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.

  • Working independently in small teams

    Official

    Supercell describes deliberately small teams with little process and says it looks for proactive doers who do well in that setting. The process focuses on whether you fit and on showing you what working there is like.

Gaurav Sen: System Design

Gaurav Sen's YouTube channel, one of the first to make system design approachable, with whiteboard-style walkthroughs of scaling, sharding, consistent hashing, message queues, rate limiting and classic interview designs. He reasons through problems on camera, including discarded first ideas, rather than presenting a finished answer. The channel has about 758k subscribers. It is a good free starting point for system design before committing money to a course.

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 Supercell 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.

How to actually get seen

Apply as soon as you see a relevant role, since applications are reviewed on a rolling basis and there is no open application route. Applicants from abroad are welcome, and Supercell helps with relocation if you are hired.

Processes change, rounds get added, tests get replaced. If what you went through was different from what is on this page, tell me and I will update it.

Want me to refer you here?

Send me the role, your CV and a few honest paragraphs on why you fit it. Where I know someone inside and your profile matches, I will make the introduction. Where I cannot, I will tell you why and point you at the route that does work. You get an answer either way.
