Overall the interview process at Datadog was great. In total, from first contact to the end of the process it took about 5 weeks, this was mostly just due to my availability and a holiday falling within the time period I was interviewing. Process started with a call with recruiter asking the usual questions (background about myself, experience, etc and to tell me more about the role). The recuriter provided information and let me know what to expect with each round of the interview, though the Datadog website also has good information on their career's page about the candidate experience. Second round was a 30 min call with one of the hiring managers where again they told me about the role, and the company/team culture and just wanted to get to know me more. I don't recall the exact questions they asked, but how points on my resume aligned with the role, like documentation or training I had done in previous roles and how I approached doing that. I'd say really just be ready to provide examples of what you did in your previous role. The next round was a take home assesment test on hacker rank. I won't say what the exact questions were but I will say you should be familiar with SQL, review their documentation to understand how to install/configure their agent, and be familiar with Bash scripting. The final round interview was a 2.5 hour onsite/virtual with two managers for more of a behavioral interview and 2 people from the team to do more technical interviewing, and finally with the director of the group. The behavioral part with the two managers is questions just around things like how do you handle certain situations, tell me about a time you had to do X,Y or Z, questions about cross collaborative work, etc. And honestly I'd say the interview with the director is much the same. The technical piece has 4 questions they gave me prior, all related to the solution I'd be supporting and you can utilize their documentation and other knoweledge to answer those questions prior to your onsite, and then you just exaplain your answers. Then they ask 2 questions on the spot for you to do a bit of troubleshooting which you can look up online in their documentation to help answer if needed. Overall my advice is to familiraize yourself with the documentation, at least how to do the basics, install/configure things, and if you can use the trial account you get access to when doing the take home assesment to install the solution on your own system so you get some hands on. Otherwise what I see is Datadog values people who don't have an ego, are humble and willing to be open and share with others in respect to your knowledge and expertise.
