TikTok Interview Process
The TikTok interview process includes:
- A recruiter phone screen or email questionnaire,
- Technical screens (2-3 rounds of coding challenges or virtual interviews),
- Final round interviews with a hiring manager and HR.
TikTok has a fast-moving interview process that typically completes within one month. The company conducts all interviews virtually with no on-site final rounds.
How long does the interview process take?
TikTok's interview process typically takes about 4 weeks from initial application to final decision.
The timeline is notably swift, with recruiters following up within a week between rounds to maintain momentum throughout the process.
Does TikTok's interview process vary by role?
TikTok's interview process is not standardized and varies significantly by role, experience level, and even between candidates applying for the same position.
Technical roles emphasize multiple coding challenges and domain-specific interviews, while non-technical roles focus more on leadership interviews and take-home assignments.
What is the format of the interviews?
All TikTok interviews are conducted remotely, lasting between 45 minutes and one hour each. Expect video calls for each round, except for the initial recruiter call, which is conducted over the phone.
Interviewers may be located in different time zones or countries, so prepare for interviews scheduled outside typical business hours to accommodate global teams.
What about for students and new grads?
Interviews for students and new grads are different. They include a pre-screening by a recruiter, then a one- to two-hour online interview or assessment event on HackerRank.
These events often include many applicants at once.
Recruiter Screen
The interview process at TikTok begins with either a recruiter phone screen or an email questionnaire that serves as the initial evaluation.
This screening assesses basic fit, availability, and alignment with TikTok's mission and values before advancing to technical rounds.
How should I prepare for the recruiter screen?
Prepare to discuss your resume and how your experience aligns with TikTok's mission to “inspire creativity and bring joy.”
Spend time understanding TikTok’s philosophy and leadership style, which prioritize an entrepreneurial mindset, pragmatism, ambition, and goal setting.
Research TikTok's products, features, and recent company news, and develop specific examples demonstrating how your experience aligns with the company's mission and values.
Technical Screens
After the recruiter screen, you'll advance to 2-3 rounds of technical screens that represent the most challenging phase of TikTok's interview process.
What are TikTok's technical screens for technical roles?
Technical roles complete 1-2 online coding challenges on HackerRank featuring medium to hard difficulty problems.
These assessments are followed by additional virtual technical interviews covering system design or machine learning, typically scheduled on the same day or a few days apart.
What about non-technical roles?
Non-technical candidates participate in 2-3 interviews with team leaders, hiring managers, or skip-level managers from relevant departments.
Expect behavioral, hypothetical, and domain-specific questions. You may also get a take-home assignment, such as a product case study for Product Management roles, to present during interviews.
How should students and new graduates prepare?
Student and new graduate opportunities open in August and September across all regions.
After initial recruiter pre-screening, candidates complete a one- to two-hour online assessment event on HackerRank, often with many applicants simultaneously. Top scorers receive priority, though lower-scoring candidates may still advance.
Final Round Interviews
What is TikTok's final round?
The final round consists of two separate virtual interviews: one with the hiring manager and one with HR.
Each interview lasts 45 minutes to one hour and focuses on cultural fit, domain knowledge, and behavioral assessment.
Final round with a hiring manager
The hiring manager interview combines behavioral questions and domain knowledge evaluation.
Expect an in-depth discussion of your resume and detailed questions about past projects relevant to the team and role you're pursuing.
Final round with HR
The HR interview resembles the initial recruiter screen but goes deeper into cultural fit assessment.
Prepare behavioral examples demonstrating why you want to work at TikTok and how you embody the company's mission and values. Some candidates receive offers during this final HR conversation.
How does TikTok evaluate cultural fit?
TikTok assesses alignment with its core values: empowering creators, connecting people, and exploring possibilities.
Prepare specific examples demonstrating creativity, innovation, and leadership in your past experiences and decision-making processes.
What should I research before the final rounds?
Familiarize yourself thoroughly with TikTok's app, features, and product ecosystem, as well as relevant news, trends, and competitors in the sector.
Study recent company developments from TikTok's newsroom and explore initiatives like TikTok for Good and TikTok for Developers to demonstrate a genuine commitment to the company.
