Not much is known about Uber's front end interview process.

JavaScript coding questions​

  • Implement a rate limiter attribute/decoration/annotation on top of an API endpoint. Caps to N requests per minute with a rolling window. Source A and Source B

User interface coding questions​

  • Create a button that when clicked, adds a progress bar onto the page. The progress bar would then fill up in a given amount of time (think 3 to 5 seconds). If you get past the first part, you will be asked to do throttling how many progress bars can be running at once. For example, if the limit is 3 progress bars, and the user clicks on the button 4 times, the fourth progress bar only starts after the very first one finishes. Source
  • Overlapping circles app. Source

3rd Jun 2025:

I was asked a reactjs based question although I majorly prepared for dsa and JS type questions based on the questions asked previously. What I've learned and observed about Uber's FE process is that they can ask pretty random questions. I guess recruiters are not in sync with the interviewers. Or it feels like it is more up to the interviewers on what they ask. I watched some YT videos of people on their uber interview experience and literally to each one of them dsa was asked.

Just gave BPS round of Uber and gotta say, Uber has quality problems! I thought it would be DSA as the recruiter had mentioned. But I guess you can’t trust recruiters nowadays. Question was “create a utility in JS to send data in batches with a timeout. So, as soon as a batch size is reached, send the data right away and start the timeout. If timeout happens before batch is filled, send the batch as it is and start the timer again.” Also, I asked the interviewer for what to prepare for DSA round and he said array, trees, graphs, traversals, but he also mentioned that Uber is trying to get away from DSA for frontend roles and keep it frontend focused and slowly they are doing it.
