DSA Mock Interview for FAANG and Product Companies

general

About This Service

A realistic 60-minute DSA mock interview using questions aligned with your target company and experience level. Receive detailed feedback on problem solving, coding, communication, correctness, and time management.

Practice a realistic Data Structures and Algorithms interview modeled around the expectations of FAANG and top product companies.

The session follows an actual coding-interview format rather than a guided tutoring session. You will be expected to clarify the problem, discuss possible approaches, select appropriate data structures, write correct code, analyze complexity, and respond to follow-up questions.

I have conducted more than 100 interviews across Google, Amazon, and Microsoft, allowing the session to incorporate both candidate and interviewer perspectives. 

What is evaluated

  • Problem clarification
  • Identification of edge cases
  • Choice of data structures and algorithms
  • Ability to move from brute force to an optimized solution
  • Correctness of the final implementation
  • Time and space complexity analysis
  • Code quality and readability
  • Testing and debugging
  • Communication with the interviewer
  • Use of hints
  • Time management throughout the interview

Interview difficulty

The question will be selected based on:

  • Your experience level
  • Target company
  • Target role
  • Current preparation
  • Preferred programming language
  • Requested difficulty

Feedback after the interview

You receive a structured breakdown of:

  • What went well
  • Where you lost interview signal
  • Technical gaps
  • Communication gaps
  • Missed edge cases
  • Better approaches
  • How your performance compares with the expected hiring bar
  • What to practice next

Best suited for

  • Candidates preparing for coding rounds at product companies
  • Engineers who solve problems independently but struggle during interviews
  • Candidates who need to improve communication and pacing
  • Engineers preparing for Google, Amazon, Microsoft, Uber, Meta, and similar companies
  • Candidates returning to DSA after several years of professional experience

This session is designed to reveal how you perform under interview conditions, not merely whether you can eventually solve the problem.

Parminder Poonian

Parminder Poonian

Senior Software Engineer at Uber

Ex-Google, Microsoft and Amazon | 100+ Technical Interviews Conducted I help software engineers prepare for interviews at FAANG, MAANG, and top product-based companies through personalized mentorship, realistic mock interviews, resume reviews, and career guidance. I started my career from a Tier-3 college and now have more than 7 years of experience working at companies including Uber, Google, Microsoft, and Amazon. During this journey, I have built large-scale systems, led high-impact engineering projects, contributed across backend development, machine learning, frontend engineering, databases, and compiler-related systems, and conducted over 100 technical interviews. My mentorship is designed for software engineers who want practical guidance rather than generic interview advice. Sessions are tailored to your target company, experience level, preparation timeline, and specific gaps. I can help you with: * DSA and coding interview preparation * Backend system design and distributed systems * Multithreading and concurrency interviews * Machine learning interviews * Behavioral and hiring-manager rounds * Software engineer resume reviews * Senior Software Engineer interview preparation * Personalized career and job-switch roadmaps * Long-term software engineering mentorship You will receive honest, detailed, and actionable feedback based on how interviewers evaluate candidates. The objective is not just to help you learn more concepts, but to improve how effectively you demonstrate technical depth, ownership, communication, and engineering judgment during interviews.
