      Software Engineer Interview

      Negative experience
      Easy interview

      Application

      I applied online. The process took 1 week. I interviewed at 21.co in Apr 2023

      Interview

      Brief video screen and then take home. Take home asked questions about techs not on job description. I emailed recruiter asking about this and if I received the wrong take home. I was ignored until an auto rejection email was sent. It makes no sense to ask Python and Vue questions on a position that is strictly JavaScript, React, and NextJs (of which there were no questions for!?) What a joke and waste of my time, but falls in line with what I was expecting based on the reviews of this organization.

      Interview questions [1]

      Question 1

      Some behavioral with outdated terminology and tone indicative of a toxic work culture. Ie: “Are you comfortable giving criticism to your coworkers?” Incredibly basic react question. No where near difficult enough to accurately gauge the technical proficiency of the interviewer, but at least I didn’t waste too much time on it.
