      Positive experience
      Average interview

      Application

      I applied online. The process took 3 weeks. I interviewed at Datadog (New York, NY) in Oct 2019

      Interview

      1. HR intro call 2. 1-hour tech screen - 2 leetcode mediums 3. Take-home project (~3 hours) - build an alert/logging application with tests + docs 4. 3-round on-site. One coding (LC medium), one with hiring manager asking about a past project in depth, one system design (design Datadog). Recruiter and everyone I spoke with were all great, unfortunately I blew the system design round. Very quick turnaround of 1-2 days between each stage.

      I interviewed at Datadog

      Interview

      El proceso constó de tres fases principales. Primero, apliqué online a un puesto de trabajo disponible. Posteriormente, pasé a una entrevista técnica de aproximadamente una hora, enfocada principalmente en el desarrollo, integración y securización de APIs. También discutimos estrategias de despliegue, monitorización y gestión de recursos en la nube utilizando el ecosistema de Azure. Por último, realizamos un ejercicio conversacional sobre buenas prácticas de código y arquitectura. Fue un proceso fluido y el equipo fue muy profesional.
