Where to apply

Ask for a referral to Celonis

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

Celonis publishes one company-wide process rather than an engineering-specific one, and the challenge round only applies to some roles. The process typically takes 1 to 2 months.

  1. 1

    Recruiter chat

    Official
    Recruiter screen

    A conversation with a talent acquisition specialist about your background, your goals and how you might fit the team.

  2. 2

    Follow-up interview

    Official
    Hiring manager

    You meet the recruiter, the hiring manager or other team members to go deeper into the role and your experience.

  3. 3

    Challenge round

    Official
    Technical interview

    For some roles you complete a challenge that shows how you think critically and solve problems. The recruiter shares the details in advance.

  4. 4

    Executive interview

    Official
    Senior leadership

    A final interview with the executive who leads the function you would join.

  5. 5

    Hiring decision and offer

    Official
    Offer

    The team reviews candidates and the recruiter contacts the chosen one with an offer covering pay and benefits.

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.

  • Problem solving

    Official

    The challenge round is designed to show how you think critically and work through a problem.

  • Motivation and authenticity

    Official

    Recruiters say they want to see what genuinely motivates and excites you, so be yourself.

Platform
Hack The Box Academy

Hack The Box's structured course platform, built from short modules rather than the open ended machines the main HTB site is known for. Its Tier 0 fundamentals modules are effectively free, and job role paths such as SOC Analyst and Penetration Tester lead into HTB's own practical certifications.

LetsDefend

A blue team focused training platform built around a simulated Security Operations Centre, where you investigate real looking alerts, phishing emails, and malware samples the way a working SOC analyst would.

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 Celonis 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?

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.
