I went through five rounds of interviews at TikTok. Overall, the process was well-structured and professionally conducted. The recruiter was excellent—responsive, organized, and supportive throughout the entire experience. Most interviewers were prepared and respectful, although one of the early interviewers did not appear to know the specifics of the role I was interviewing for, which was surprising and a bit disorienting. The final interview was with an HR Business Partner (HRBP)—a unique role at TikTok instead of a traditional HR representative. I appreciated her transparency about the team's dynamic and expectations, though I was concerned when she shared that she had been working from 6 AM to 10 PM without breaks shortly after joining the team. While it was framed as dedication, it also gave me a glimpse into a potentially unsustainable work culture. Offer and Post-Offer Experience: I accepted the offer primarily because I felt aligned with the hiring manager, who was experienced and shared my values. Unfortunately, he resigned just before my official start date. My new manager was based in China, and when I requested a minor shift in working hours to accommodate school pick-up for my children (something the original manager had agreed to), it was declined. This was particularly disheartening given the expectation to attend evening meetings. It became clear that there was little room for flexibility, and ultimately, I had to decline the offer. The interview process at TikTok is polished and well-managed, but be aware: if you value work-life balance or have family responsibilities, this may not be the right environment for you. Flexibility is limited, especially when working with teams across time zones, and expectations around availability can be extreme. Make sure to get clear answers about working hours and team culture before committing.
