I applied through a recruiter. The process took 1 week. I interviewed at Nextdoor in Aug 2025
Interview
Recruiter reached out and scheduled tech screen which had 2 rounds of interview. Both interviews were for 1 hour each. No behavioral.
1st interview asked something similar to Secret Santa and started from very basic condition and slowly added contraints one by one. My solution worked for initial constraints but last case couldn't handle. With last constraint it felt almost the problem become an n-queens problem.
For second round, interviewer asked storing the comments of a post which had references to its parent in such a way that its easy to traverse them and print the list of comments in hierarchical manner. Would say to practice storing objects and their references in a map, such that with dfs you can print those.
Both interviewers tried to help out and were actively working with me on the solution. For second round, I took too much hint, may be that's why I didn't clear it.
Interview questions [1]
Question 1
Build data structure to hold comment and comment node and print comments in hierarchical manner
phone call into coding screen
coding screen -> full loop but decided to stop after passing the coding screen
next is the typical 4-5 hr interview day with coding, system design, behavioral, etc
standard 3 rounds of LC style coding, 1 system design, 1 behavior round. Passed all rounds but no matching team, no offer. Don't think they have a candidate pool that will keep you for a while. So make sure you have the team aligned before doing the interview; otherwise do not waste your time.
Interview questions [1]
Question 1
LC style question, medium to hard with a couple of follow-ups.
I applied through an employee referral. I interviewed at Nextdoor
Interview
I began by speaking with the recruiter to understand the role and expectations. After that, I completed two technical coding screens. I then participated in a five-person panel interview, which included the hiring manager and involved additional coding exercises as well as a deeper discussion of system and architectural design.

Question 1
The coding questions are straightforward and don’t include any tricks. Nextdoor keeps the problems closely aligned with their actual products, making them feel like realistic tasks you might handle as an employee.
