02 / Hiring process
Four stages, and one of them decides it
4 stages from application to offer. Coding round is reported to be the one that decides it.
4stages
01
Initial screen phone or Zoom, with a recruiter or hiring manager
Datadog's own page describes this as a conversation for the hiring team to get to know you and for you to share your career aspirations, usually with the recruiter or hiring manager.
02
Coding round live pair programming, real systems-level problems
Reported for technical roles as live pair programming, often in CoderPad, built around real systems-level scenarios such as a metrics aggregator or a log parser under a specific performance constraint, rather than an abstract puzzle.
03
Face-to-face interview loop 3 to 5 rounds, one is expected in person
Datadog's own page describes this as multiple rounds or panels with the recruiter, hiring manager and team members. For engineering, this is reported to include a system design discussion, a project deep dive defending real past decisions, and a debugging round built around a broken service or anomalous metrics.
04
Take-home, executive round and selection role dependent, then an offer
Datadog's own page describes an optional take-home project and, for some roles, a final executive interview, before the interviewing team meets to select a candidate and the recruiter follows up with an offer.
Ask before the interview: what will this round cover, who will I meet, and is there anything I should prepare?The question almost nobody asks
03 / Question library
Interview question practice library
The coding round, the face-to-face loop and the three named engineering culture values apply broadly, so the core set below covers that ground. Each department then adds the depth specific to it.

What happened at this employer this month
Stories screened from everything published about this employer, chosen because they can be used in the room rather than because they are recent.
- Each one carries a line on how to use it in the answer
- Crime, recalls, litigation and share price moves are excluded outright
- Refreshed daily, so it is different the week of your interview
05 / The three values
What is actually being scored
Datadog does not publish a single numbered company-wide values list. Its own engineering job postings do consistently name three engineering culture values in this exact language. Bring one real story for each rather than a general answer about liking observability tools.
3stories
Pragmatism
A time you chose the practical solution that actually shipped over a more elegant one that would have taken far longer.
Honesty
A time you told someone something they didn't want to hear because it was accurate.
Simplicity
A time you simplified something complex specifically so the next person could actually maintain it.
06 / Before you apply
Where candidates lose it
Pro
Where candidates lose this before anyone meets them
The part of the process that eliminates most people is not the interview. It is what happens around it, and almost none of it is written down anywhere.
- The assessment answers that read as dishonest rather than confident
- What the availability question is really deciding
- The application detail that cannot be edited once submitted
