The interview process at Meta (formerly Facebook) typically involves several stages, which can vary slightly depending on the role, level, and location. For software engineering positions, the process generally includes:

1. Initial Screen:

   • Recruiter Screen: A discussion with a recruiter about your background, experiences, and the role you’re applying for.
   • Technical Screen: This often involves one or two technical phone interviews with a coder pad or an online coding platform. You're expected to solve coding problems in real-time focusing on data structures and algorithms.

2. Onsite Interviews:

   • For candidates who pass the initial screening, the next step is usually a series of onsite interviews (which might be virtual due to circumstances like the COVID-19 pandemic). These typically include 4-5 rounds covering:
     • Coding Interviews (2-3 rounds): Focused on data structures, algorithms, and problem-solving skills.
     • System Design Interview: Evaluates your ability to design large-scale systems.
     • Behavioral Interview (also known as the "Jedi" interview at Meta): Focuses on assessing your ability to work in a team, leadership qualities, and alignment with Meta's core values.

3. Specialized Interviews (depending on the role):

   • Domain-Specific Technical Interviews: For certain positions, there may be interviews focusing on specific technical knowledge or skills relevant to the role, such as machine learning, front-end technologies, or backend systems.
   • Career Background Interview: Some candidates might also have an interview focusing on their past work and projects.

4. Hiring Committee Review:

   • After the interviews, the feedback from all interviewers is compiled and reviewed by a hiring committee. This committee makes the final decision on whether to extend an offer.

5. Offer Stage:

   • If the decision is positive, the recruiter will discuss the offer details, including compensation, benefits, and start date.

The entire process from the initial application to receiving an offer can take several weeks to a couple of months, depending on various factors like scheduling availability, role urgency, and internal processes.
