I applied online. I interviewed at Datadog (Lisbon, Lisbon District) in Jun 2026
Interview
First, I submitted my resume and application online through the job portal. A recruiter reached out for a brief video call. This was just to chat about my background, salary expectations, and basic fit for the role.
Next I met with two managers. They dived deep into my experience, and I transitioned into a live roleplay scenario at the end of the call so that they could test my practical skills. I didn't get through, received an e-mail last week.
Recruitment process includes an initial HR interview, a HackerRank technical assessment, an intermediate live coding interview, a more advanced live coding interview, and a final system design interview. Everyone was very nice and encouraging !
