      Software Engineer Interview

      13 Feb 2021
      Anonymous interview candidate
      Madrid
      No offer
      Positive experience
      Average interview

      Application

      I applied online. I interviewed at Datadog (Madrid) in Jan 2021

      Interview

      First, I talked with the recruiter about what I was looking for, their open opportunities, the one I have applied, etc. After that, I had a phone interview with an engineer. He was very kind. The first part was a presentation from both sides and then to talk about a project you did. He did a very good question regarding one of the tools and my answer was not so clear. After that, he asked me a LC easy that I did very fast and then more like a LC medium that I had problems with. The process would have continued with a take home project before a final loop of interviews.

      Interview questions [2]

      Question 1

      A dictionary common question (LC easy).
      Answer question

      Question 2

      Given a list of tuples representing a metric during time like (x,y), interpolate the missing values.

      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.
