Ask for a referral to Datadog

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

Datadog notes that the flow varies by role and team, some roles include a take-home project, and one in-person office visit is expected at some point. Candidates report that team matching happens after the onsite, and that weaker system design performance can lead to a lower level offer.

  1. 1

    Initial screen

    Official
    Recruiter screenRemote

    A phone or Zoom conversation with a recruiter or hiring manager about your background and what you are looking for.

  2. 2

    Technical phone screen in CoderPad

    Reported +1
    Live coding1 hoursRemote

    Usually two practical coding questions that start simple and add complexity, drawn from Datadog’s own question bank rather than well-known puzzles.

  3. 3

    Onsite: coding and system design

    Reported +1
    Panel interview

    Datadog says this stage may be several rounds or panels, virtual or in person. Engineers report one or two further coding rounds and a one-hour system design interview.

    CodingSystem design
  4. 4

    Behavioural interview with a manager or director

    Reported
    Hiring manager1 hours

    Questions about past projects, your technical decisions and how you worked with others. Staff level candidates also give a presentation of previous work.

  5. 5

    Executive interview (some roles)

    Official
    Senior leadership

    For some roles a final conversation with an executive leader about your experience and the wider team.

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.

  • Practical coding problems

    Reported

    Examples reported include computing directory sizes or building a buffered file writer behind an interface.

  • Focused system design

    Reported

    Design questions are narrower than typical industry prompts, for example a service that notifies users about newly matching flights.

  • Rules on AI use

    Official

    AI tools are banned in live coding and non-technical interviews unless announced, but some engineering roles have a dedicated AI-focused coding interview where their use is expected.

Guide
Design Docs at Google

A short, widely shared essay by Malte Ubl, a former Google principal engineer, on how design docs work at Google: what sections to include (context and scope, goals and non-goals, the design, alternatives considered, cross-cutting concerns), how long they should be, how review works and when not to write one. For engineers asked to write their first design doc or improve how their team does them.

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 Datadog 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

Check with your recruiter whether your loop includes an AI-assisted round, because AI use anywhere else can disqualify you. Practise explaining the reasoning behind design decisions from your own past projects.

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.
