Interview Process (5 rounds):
Initial HR screening (30 mins)
Technical screening with team member (1 hour)
Technical challenge: Bot detection JS implementation
Technical screening with team leader (1 hour)
Technical interview with senior researcher (1 hour)
Interview Questions:
Detailed discussion about previous experience with bot detections and detection solutions, including research projects
System design: How would you research bot detection feature?
What are the techniques may be used to detect verified bots using JS?
Technical deep-dive JS and DOM elements, including questions about how to manipulate unwritable JS objects.
The Good:
The interviewers were knowledgeable and respectful. The technical challenge was relevant to actual work, focusing on bot detection patterns rather than abstract algorithms. They gave me adequate time to think through problems.
The Bad:
The process took 5 weeks total, slightly longer than expected. Some overlap in questions between rounds. The take-home challenge took longer than the suggested 4 hours.
