Interview Process

Once you know which candidates you’d like to interview, you’re ready to begin the interview process. We recommend the following step-by-step interview process:

  1. Phone screen: A call that takes 10 to 15 minutes where the potential candidate is given general information about Fullstack Labs and is asked four to five general questions regarding their professional experience. We also assess the candidate’s communication skills as well as salary expectations. 
  2. General Coding Assessment (GCA): A standardized test that helps us measure core programming and computer science knowledge. This standard test is provided by CodeSignal. We only move forward with candidates that achieve a score of 650+.
  3. First Interview: A 60-minute interview to dig into their past extensively. We evaluate the candidate’s job history and dig into significant projects the candidate has participated in.
  4. Take-home coding challenge: An assignment that the candidates record via video with specific technical tasks to complete. 
  5. Coding challenge review: The coding challenge is reviewed by our CTO, Mike Piccolo, to see if it was done correctly and is assigned a grade. 
  6. Final Interview: If the candidate succeeded with the take-home challenge, they have a final interview with our CTO and CIO. We invest significant time from our CTO or CIO to recruit the right high-quality applicants.
