I applied online for an iOS Developer position at TikTok (ByteDance) and went through their interview process in early 2024.
The entire experience, while short, was structured and professionally handled.
Application Process 🚀
The first step was a recruiter screening call. It was a fairly standard conversation — mostly focused on my resume, prior experience, and availability.
There was no technical discussion in this stage. However, there was a notable gap of about one month before the next step was scheduled, likely due to internal timelines or volume of applicants.
Technical Interview
The second round was a 45-minute technical interview conducted over Zoom. It included:
- A discussion about my previous iOS development experience, particularly around real-world project decisions.
- A set of basic iOS-related questions, touching on common topics like the view controller lifecycle, memory management, multithreading, and delegate vs. notification patterns.
- A LeetCode-style medium-level algorithm problem, focused on string manipulation. I was able to complete it correctly within time, and the interviewer mentioned that my solution appeared optimal in terms of runtime and space complexity.
✅ Before this interview, TikTok provided a detailed preparation document, outlining the structure of the interview and key topics to focus on.
This guide was genuinely helpful and aligned well with the actual questions asked.
