How to Get Hired at pubmatic

PubMatic is one of the leading independent programmatic advertising platforms, listed on NASDAQ and with a major engineering centre in Pune. The company builds technology that helps digital publishers maximise revenue from their ad inventory through real-time bidding and programmatic ad buying. India is not a support hub here. Pune contributes to core product engineering, meaning engineers here work on systems that handle billions of ad requests daily.

As of July 2026, PubMatic has 62 open roles across functions. Engineering makes up the bulk of these, covering backend development, data infrastructure, machine learning, and DevOps. Product management, sales, and operations positions are also listed. The variety means both technical and non-technical professionals have a realistic shot depending on experience.

For engineers who want to work on genuinely interesting scale problems in a growing domain, PubMatic is worth targeting. Ad tech infrastructure is technically demanding, and PubMatic's position as an independent platform (not part of a larger conglomerate) means engineers often get broader ownership than at bigger companies.

PubMatic's hiring process is structured and fairly consistent across engineering roles, though the exact number of rounds can vary by team and seniority. Candidates typically report four to six rounds from application to offer.

Most candidates report the full process taking two to four weeks from first contact to offer, though this can stretch longer for senior roles or if teams are moving slowly.

PubMatic engineering teams want people who can build and reason about systems that run at serious scale. Here is what typically matters across roles:

Strong coding fundamentals. The coding rounds focus on data structures, algorithms, and clean problem-solving. Java and C++ are the most common languages in PubMatic's stack, with Python and Go also appearing. Practise in whichever language you are most fluent in.

Distributed systems understanding. PubMatic's core product processes ad bids in real time with very low latency. Understanding message queues, caching strategies, database sharding, and high-throughput pipeline design is important for mid-to-senior roles.

Domain curiosity. You do not need prior ad tech experience to get in, but interviewers appreciate candidates who have read about programmatic advertising and real-time bidding. It signals genuine interest beyond just a job change.

Ownership and accountability. PubMatic expects engineers to own their work end-to-end and understand the business context of what they build. In interviews, highlight examples where you designed, built, and shipped something without heavy guidance.

Communication skills. Teams work across Pune and US time zones, so clear, concise communication (both written and spoken) matters more than you might expect.

Start with coding practice. Spend focused time on LeetCode or GeeksforGeeks solving medium and hard problems in categories PubMatic commonly tests: arrays, linked lists, trees, graphs, dynamic programming, and sliding window. Consistency over several weeks beats last-minute cramming.

Build your system design knowledge. For roles above entry level, prepare to walk through designing a real-time bidding system, a logging pipeline, or a large-scale data aggregation service. Books like 'System Design Interview' by Alex Xu are commonly cited as useful preparation resources by candidates across the industry.

Learn the ad tech domain. Spend a few hours understanding how real-time bidding works, what the difference between a DSP and SSP is, and how publishers earn revenue from programmatic ads. PubMatic's engineering blog has publicly available technical articles that give useful context.

Tailor your resume. Highlight distributed systems work, high-throughput data processing, or any product-scale experience. Quantify your own impact using numbers you actually own from your projects.

Prepare your story for the HR round. Be ready to explain why you want to join PubMatic specifically, how you handle disagreements with teammates, and what you are looking for in your next role. Honest, clear answers work better than rehearsed ones.

knok checks 150+ job sites nightly, applies to roles that match your resume, and messages HR on your behalf, which can help you get faster visibility into PubMatic's active openings.

PubMatic describes itself as an engineering-first company, and the Pune office reflects that. Engineers here are not doing maintenance or second-tier work. They contribute to core product features and infrastructure used by publishers and advertisers worldwide.

Ownership culture. The expectation is that you own problems, not just tasks. Engineers are encouraged to understand why they are building something, not just what. This can feel demanding if you are used to highly defined ticket-driven work, but it also means more scope and visibility.

Cross-timezone collaboration. Working with teams in the US is a regular part of life here, particularly for senior engineers and team leads. Some flexibility in working hours is typically expected to overlap with US counterparts.

Learning and technical depth. PubMatic publicly reports investing in employee development, and the nature of the work (large-scale ad infrastructure, real-time systems) naturally pushes engineers to grow technically. If you want to go deep on distributed systems or data engineering, the environment supports that.

Pace and structure. Current and former employees commonly describe the workplace as demanding but reasonably structured. It is not chaotic startup energy, but it is not a slow-paced corporate environment either. The expectation is consistent, high-quality output.
