Behavioral Coding System Design
I was approached on LinkedIn for this role. The first stage was a 30-minute hiring manager interview, which was mainly focused on my past projects. After that, I got scheduled for a 1-hour screen interview. This interview had two parts: a LeetCode Medium problem and a System Design question. The interviewers didn't introduce themselves or explain their roles. They immediately started with the programming question, followed by System Design, which felt like a lot for just one hour. Unfortunately, I didn't pass this round.

Behavioral Technical Case
Interviewing with StackAdapt was a great process. I applied through their website after seeing the job on LinkedIn. My first meeting was with a recruiter, who asked about my background to see if I'd be a good fit. Next, I talked with the department manager about my past experience and projects. He then sent me a case study to complete, which had some questions that were easy to answer if you know the systems and languages. I put a lot of work into making it concise and professional. The final meeting was with the same manager and the Director to present the case study. They were welcoming and great during the presentation. Their questions were clear and they were interested in what I had to say. I received my offer the next day.

Technical Coding
Had an intro chat with the recruiter for about 30 mins, then another 30 min chat with the Engineering Manager where they asked some basic Javascript questions like console.log(Boolean({})). After that, there was a 1-hour FE pairing interview where I had to find bugs in a small React app and add a new feature. Didn't make it past this stage even though I fixed all bugs and added the feature. Recruiter communication was also a bit slow, had to follow up a few times.
Confirmed questions4 questions
- What is the output of console.log(Boolean({}))?
- What result does console.log(Boolean(NaN)) yield?
- Could you debug and fix the issues in the provided React code?
StackAdapt Software Engineer Interview Questions
Quoted word for word from StackAdapt interview reports.
“Given a text string and a two-character pattern string (both lowercase English letters), you can insert either character of the pattern into the text exactly once (at any position, including ends). What's the maximum number of times the pattern can appear as a subsequence in the modified text? A subsequence is formed by deleting zero or more characters from a string without changing the order of the remaining characters.”
