I applied through a staffing agency. I interviewed at Addepar (New York, NY) in May 2021
Interview
The interviewer was yelling at me in system design (Design Slack of 1000 people) interview :) Would not let me finish my sentences. Would not allow me to take the floor to finish my thought process. I think he wanted a prepared and orchestrated answer like you find on web.
Surprisingly none of the 3-4 interview rounds I gave, the interviewees asked me about my 7 years of experience or projects. Direct jump to questions. Makes me wonder about the essence of candidate evaluation.
The interview process just makes me value my current job even more. I realized mid way, this is not the place to go
Interview questions [1]
Question 1
Non leet code questions. They have personalized questions. Though I would say quality of coding questions were good
I am sorry to hear you had a poor interview experience. I will share this feedback with the engineering teams and look to make improvements.

Interview
I applied for a Frontend role and had an initial 30-minute discussion with HR over Zoom/Meet. After that, there was a DSA knockout round, which I cleared.
Following this, three interviews were scheduled: two technical rounds and one managerial/behavioral round.
The technical interviews were quite unique—focused on areas not typically asked in frontend interviews. They required fast problem-solving, strong familiarity with DOM APIs, and handling grid-based calculations. These are definitely areas that need specific practice.
The final round went average. I was able to discuss a partial solution, but due to time constraints, I couldn't fully complete it.
I was eventually rejected. I felt I performed well enough to move forward, but it seems every round needed to be near-perfect to progress.
Interview questions [3]
Question 1
DSA question - need to create a recursively tree type structure.
On a sorting algorithm, we need to create a visual representation of the sorting algorithm in JS, where after each second we should see the elements shuffling in the array, and finally the sorted array.
I applied online. I interviewed at Addepar in Jun 2025
Interview
30 min initial screening call with recruiter. 1 hour basic coding screening test. Then 3 interviews in a day that included 1 hour coding test, 1 hour system design test, and 1 hour behavioral interview, each one with a different set of people. Almost everyone was punctual and cordial but I don't think the system design test was executed in a way that could give any candidate a fair evaluation. I had a workable MVP for the question that was asked of me but didn't get a chance to develop it in time as I kept being interrupted by the interviewer asking me deep dive questions about what I was putting on the whiteboard. Got feedback from the recruiter who told me I did well in all the rounds except the system design and they thus decided not to proceed with my application.
