Process
Very good and clear hiring process. People are helpful.
Interviewers were nice, and HRs were quite helpful. I particularly enjoyed the speed and transparency of the process. All steps were described in detail, as well as materials shared to prepare for the interviews.
The interviews themselves were moderately difficult.
- Coding interviews were about LeetCode medium level, but wrapped in Datadog specifics.
- Design interviews were more demanding, requiring some deep diving into technologies chosen.
- Behavioral interviews were also standard, somewhat similar to Amazon's LP. Preparing stories in the STAR method is good advice.
Overall, a very good process. I enjoyed it from start to finish.
Questions
One of the interviews requires presenting some design problem from your own experience. This is quite a refreshing take on the design interview: you need to present the problem, the solution, and the trade-offs taken.
Other sections are more standard.

Senior Software Engineer • Current Employee

Pros: Hiring process:
The whole hiring process was great. The recruiters always told me about the next steps and what else was missing in the process. The process went quite quickly (in fact, I slowed it down a bit because I was doing another process). At the end, I had a team matching round where I was able to pick between 3 teams. I was also able to negotiate a pretty good compensation package.
Onboarding:
The onboarding was well organized. You have 30-day, 60-day, and 90-day "lookbacks" (reviews) to see if you're meeting expectations and what you should be focusing on. My manager is pretty hands-off and the team has been very welcoming, helping me with the ramp up and answering any questions for me.
The office:
I'm based in the Madrid office. You have to come 3 days per week. You have free lunches Monday, Wednesdays, and Fridays. Most people either come Mon-Wed or Mon/Wed/Fri. The office usually organizes office-wide activities once a month. There is a mix of international and Spanish-speakers.
The company/Exec:
IMO Exec seems to have a clear direction for the company. Things get a bit more fuzzy at the team level, with Product and Engineering disagreeing on the specifics of certain OKRs/efforts (classic Tech). Depending on your Org/team, things can feel a bit more hierarchical, but overall I've had a very good feeling of the company.
Cons: I can't think of much. The 3-days per week office policy is okay, but I really hope they don't change it. Otherwise, I know a lot of people would be unhappy.
It also depends a lot on your manager or organization. I know some people come once or twice a week, and their managers don't care. Others would get a comment in their 1-1s if they haven't come 60% of the days to the office in a given month.
