      Senior Frontend Developer Interview

      Jun 8, 2026
      Anonymous interview candidate
      No offer
      Negative experience
      Difficult interview

      Application

      I applied through a recruiter. I interviewed at Tenna in May 2026

      Interview

      The interview process included an initial recruiter screen, followed by a one-hour take-home technical assessment. The assessment consisted of a mix of JavaScript trivia-style questions and two coding feature exercises. After that, I had a one-hour interview with a team lead, which included an additional 20-minute technical assessment. The final round was a one-hour interview with the VP, which also included another technical assessment. The final assessment felt meaningfully different from the earlier stages. Rather than building on the prior assessment or evaluating clearly defined role-related skills, the VP presented problems based on technical challenges the company had previously solved internally. The expectation seemed to be that the candidate would reason their way back toward the same architectural or implementation decisions the company had already chosen, without much prior context. Overall, the process felt heavier and less transparent than expected. There were multiple technical evaluations across the process, and the final round introduced a much more difficult and company-specific problem-solving format than the earlier steps suggested. After approximately a week and a half of waiting following the final interview, I received a generic rejection email from a no-reply address. Given the number of interview rounds and assessments involved, more specific feedback or a more personal closing communication would have been appreciated.

      Interview questions [1]

      Question 1

      Pretend you have a dashboard, and on that dashboard, you have three views. The first view is a list of 100 construction vehicles and their meta-data, and it wants to have fresh data every minute. The second view is a report of 20 selected vehnicles with data on them, and their last known location - maybe consider that the person wants to follow these 20 vehicles because he thinks they aren't working. This second view wants refresh data every 30 seconds. Finally the third view is a map of all construction vehicles and their current location, it should include an option to have a heat map of the locations. It wants data every 1 second. Assume you have one web socket and it feeds in thousands of telemetry data every second. How would you solve for this?
