      Senior Software Engineer Interview

      18 Oct 2025
      Anonymous interview candidate
      New York, NY
      No offer
      Negative experience
      Difficult interview

      Application

      I applied through a recruiter. I interviewed at Integral Ad Science (New York, NY) in Aug 2025

      Interview

      HR screen, Coding interview round, need to run the code and produce required output,system design round. As an observation, the person who did the system design round seemed uninterested in listening to what I was trying to explain, frequently interrupted, at times raised his voice , frequently asked the same question without letting me finish the answer.felt that interviewer was in no mood to hire anyone.

      Interview questions [1]

      Question 1

      1)arrange all anagrams from a list of strings into list of lists. 2)Design a system, no board was given instead a coding platform was provided to just add arrows. Answered the question correctly and even checked it with different solutions provided by all great system design engineering courses. still the interviewer tried to disagree and instead started digging into my resume to question why particular design decisions were made with my current and previous workplaces.

      Senior Software Engineer Interview

      7 Sept 2023
      Anonymous interview candidate
      Declined offer
      Negative experience
      Average interview

      Application

      I applied online. I interviewed at Integral Ad Science in Jul 2023

      Interview

      There were 4 rounds of someone asking 1-3 experience question, one design, and one coding question. There was one technical conversation interview, which was more of a solution architect style interview. The interviews were pretty easy - they try to cram in a mini behavioral/system design/coding/ into each interview which is weird but ok. I was disappointed in the quality of one of the interviewers. He was a very inexperienced interviewer for someone at his career level. He arrived about 10 minutes and then blurted out instructions in a hurried tone (how else can he can make up for his tardiness, duh). So, typically at even a tier 2 company (which this place is not, apparently), if the interviewer is 10 minutes late (!!) they will bite the bullet and offer to reschedule, etc. out of professionalism. This guy actually said "Ok tell me your intro, and then immediately go into the first question which is to say something you did recently. No wait - just tell me something you did in the last two years. But something you did cool". And thats how he talked the entire interview. He would contradict his own instructions before he was even done talking lol. For the "system design" he asked a typical question about changing a batch system into a streaming system. But also for the "system design" he apparently hadn't thought through which system design tool to use. So he instead of being prepared, he insisted that I use the Zoom tool, to save time? Makes sense, because letting the candidate use a tool they are comfortable with would be silly, after all. The funny part is that some part of his brain actually thought he was making up for time (again, for him being late) by having these non-linear conversations with himself. "Pick a tool you like - NO WAIT just use this Zoom whiteboard. Yes use the Zoom whiteboard… just use the zoom whiteboard".

      Interview questions [5]

      Question 1

      1st interview - 3 coding questions, easy-medium ish. The interviewer just wanted the algorithm though, no coding. It wasn't very hard. Next part - asked some experience questions 3rd part - asked a system design question about sending out emails/texts from a very large notification system.

      Senior Software Engineer Interview

      Negative experience
      Easy interview

      Application

      I applied online. The process took 2 weeks. I interviewed at Integral Ad Science

      Interview

      First round with the recruitment team I was told the next round will be technical. Got an invite with the coderpad. A week later 2nd round with one person. Not technical, some simple questions about my previous projects, what technologies I've worked with etc. The interviewer mentioned at the end, that the next stage will be technical. I've waited til the end of the week for feedback, but nothing came in. Email sent the following week, for some info regarding the next stage or if they want to proceed. 2 weeks later still nothing, so it's pretty clear they're ghosting candidates. If you are desperate apply, but if you know your value, avoid it at all costs.

      Interview questions [1]

      Question 1

      past projects technologies you worked with (ie: cloud, docker, python, what frameworks, etc.)
