I applied online. I interviewed at FreeWheel (New York, NY) in Sept 2017
Interview
Hiring process took up to 3 weeks. I submitted my application through Comcast website I got contacted by an HR person within a week. They scheduled a phone screen to test my python skills. Phone screen was easy. Then they gave me a coding assignment to take home with no time limit. It took about 2 days for me to finish it. I emailed my solution to them. Then I was called onsite. Onsite interview was about 5 rounds. All of them were pretty easy going people. First round was with a hiring manager. It was more of a discussion about a testing problem (see question below). The next round was testing how you design test cases. Third round was code review of the coding assignment that I had submitted to make sure I was in fact the author of the code. They suggested a modification and I had to do it. The fourth round was python knowledge questions and object oriented design question. The last round was with the company VP which was mostly behavioral.
Interview questions [6]
Question 1
Drew up an overview model of their ad product and asked me if we were to add a module in a specific area how would I go about ensuring that the addition did not break the flow and also how to test the module itself.
Given a module that is supposed to take in an array or ints and gives out two arrays of odd and even numbers how would you test this module? and then lets say we add a sorting modules on the odd and even arrays then how would you test those? would you also test efficiency of the sort algorithms? Finally how do you test end to end system
given an nxn array lets say
[[3, 2, 1],
[1, 4, 5],
[6, 1, 3]]
write a function to return a list of numbers that occur in more than one row. so the answer to this input would be [1, 3]
I applied through a recruiter. I interviewed at FreeWheel in June 2026
Interview
The interview process was relatively easy. Met with 4 different people and questions were mostly based on the experience that I have across different programmatic platforms. All interviewers were laid back and easy to talk to.

I applied online. The process took 2 months. I interviewed at FreeWheel (New York, NY) in Apr 2026
Interview
Average interview process, made it to the final round but did not get an offer. For how many interviews and how long the process was I was expecting to hear back from someone rather than a workday notification. I followed up with the HR contact and they never answered. It was over two months from applying to finally hearing back I did not get the position, and about two weeks between second and third round interviews, so the process lagged.
Three rounds of interviews: HR screening, Hiring Manager one on one, and then three individual interviews with peers labeled a panel. The third round really should've just been a panel as all three asked the same questions, it took up way more time having to have three individual meetings.
Overall a fine process, communication and respect for interviewee and interviewee's time could be slightly improved.
