Big tech companies receive thousands of applications for every open role and run some of the most rigorous interview processes in the industry. The standards are high, the competition is genuinely strong, and the process is structured to filter hard. Understanding exactly what each company is testing and preparing specifically for it is the difference between candidates who pass and candidates who get rejected despite being very capable.

How big tech interviews differ from other companies

Big tech companies use structured, consistent interview processes designed to reduce bias and produce reliable hiring decisions at scale. This means: every interviewer has an assigned area to assess (leadership, problem solving, analytical thinking), there is a formal debrief process with written feedback, and the bar is consistently applied. You will not get hired because you're charming: you'll get hired because you hit the bar on the specific dimensions they're evaluating.

Non-engineering roles at big tech (product management, marketing, data, operations, business development) typically include: a recruiter screen, a hiring manager screen, a cross-functional panel (typically 4-6 people assessing different dimensions), and sometimes a written exercise or case. The entire process can take 4-8 weeks.

Behavioural questions in big tech: the bar is higher

Big tech companies use behavioural interviews but the bar for what constitutes a "good" answer is significantly higher than at most other companies. Generic STAR answers don't pass. They need to demonstrate: real complexity and ambiguity in the situation, personal impact and agency (not what "the team" did), measurable business results, and reflection on what you learned or would do differently.

Amazon specifically evaluates against its 16 Leadership Principles, each of which maps to specific behavioural questions. Knowing the principles and preparing examples that directly map to them is table stakes preparation for an Amazon interview.

Big tech behavioural question categories to prepare for
  • Working with ambiguity or incomplete information
  • Influencing without authority (cross-functional collaboration)
  • Handling conflict with a peer, manager, or stakeholder
  • Making a decision under pressure or time constraints
  • Failing or missing a goal and what you did about it
  • Raising the bar (doing more than was required)
  • Diving deep into data to solve a problem

Company-specific interview approaches

Amazon: Everything is filtered through the Leadership Principles. Prepare two to three stories per principle for the most common ones. Answers need to be highly specific and quantified.

Google: Uses a "Googleyness" dimension alongside role-specific competencies. Also known for "googley" fit assessment: intellectual humility, collaborative approach, doing the right thing. Cognitive ability and structured thinking are weighted highly.

Meta: Known for product sense interviews for PM roles, system design for engineers, and cross-functional collaboration emphasis. The culture moves fast and decisions are made quickly; your examples should reflect this.

Microsoft: Places significant weight on growth mindset and collaboration. Questions about how you learn and how you work with others are common alongside role-specific technical or domain questions.

How to prepare

Research the specific company's interview format and the specific role level. Glassdoor, Blind, and LeetCode (for engineering) all have detailed, specific interview reports. Know what dimensions will be assessed in each round and prepare examples that map directly to them.

For behavioural interviews: prepare 8-10 strong stories and practice delivering them in under two minutes each. For each story, have: the specific situation, your specific actions (not "we"), measurable results, and what you learned. Stories with clear numbers are significantly more compelling than stories without.

Frequently asked questions

How many rounds does a big tech interview typically have?
Usually four to six interview rounds after the initial recruiter screen. The virtual panel (often called a "loop") is typically four to six 45-minute sessions with different interviewers, each assessing a specific dimension. Some companies add a written exercise or additional rounds for senior roles.
Can I reapply if I'm rejected by a big tech company?
Yes, usually after a waiting period (typically 6-12 months). Many people are hired at their second or third attempt after addressing the specific feedback from their previous attempt. Getting feedback from the recruiter about which dimensions you were weakest on is valuable if they'll share it.
Do I need to know every Leadership Principle for Amazon?
Ideally yes, but focus on the 8-10 most commonly assessed in your interview loop. The recruiter can often tell you which principles will be assessed in each round. Prepare at least two examples per principle you'll be assessed on, in case the interviewer asks a follow-up that exhausts your first story.
Do big tech companies hire people without big tech experience?
Yes, regularly. They hire from consulting, finance, startups, and traditional companies. What matters is demonstrating the right competencies, scale of thinking, and ability to operate in a complex, fast-moving environment. Domain expertise (e.g. ads, healthcare, fintech) can be a specific advantage in relevant divisions.
