About Physics Wallah

**Physics Wallah — company profile** PhysicsWallah (PW) is an Indian education technology company headquartered in Noida, Uttar Pradesh. It began as a YouTube teaching channel started by Alakh Pandey in 2014 and was formally incorporated as an edtech company in 2020, co-founded by Alakh Pandey and Prateek Maheshwari. The company's stated purpose is to provide accessible and comprehensive learning at affordable prices, and it describes itself as India's largest online and hybrid learning company. Its platform, pw.live, serves students from Class 6 through Class 12 and postgraduate level, with a particular concentration on competitive-exam preparation for JEE and NEET aspirants alongside school curriculum classes 9-12. Offerings include live and recorded courses, NCERT solutions, study materials, batches and test preparation content. PW operates PW Skills (pwskills.com), a separate upskilling arm focused on technology, marketing and finance courses, and runs an online degree programme. PW entered the unicorn club, becoming one of the few Indian edtech companies to reach that status, and has been backed by investors including Lightspeed Venture Partners, whose job board carries PhysicsWallah listings. The company has publicly announced large-scale hiring, including a press release on its own site titled 'Physics Wallah to hire 2500 new employees.' PW hires across teaching, academic content creation, technology, marketing, operations and support functions, and content creation is one of its largest and most continuously staffed functions given the volume of curriculum, question banks, NCERT solutions and exam material the platform publishes. The company's hybrid model combines its online platform with physical and hybrid learning centres across India, extending its reach beyond purely digital delivery into offline classroom infrastructure. PW's founding story is unusual among Indian edtech companies in that it grew organically from free YouTube teaching content built by a practising teacher rather than from a venture-funded product launch, and affordability has remained central to how it positions its paid courses against higher-priced competitors. Its official recruitment portal is hosted on Darwinbox under the tenant PhysicsWallah Limited, linked directly from the pw.live homepage. **Industry:** EdTech / Online Education **Headquarters:** Noida, Uttar Pradesh, India **Official website:** https://www.pw.live/ **Why work here as a fresher** Physics Wallah is the kind of company where early-career talent is given real scope rather than busywork. Interns and freshers are placed on live problems, paired with experienced mentors, and reviewed on the same quality bar as everyone else. That combination — real ownership plus real feedback — is what turns a first role into a genuine career head start. **Culture** Expect a fast-paced, outcome-oriented environment with flat communication, short feedback loops and a strong bias for action. Teams are small enough that your contribution is visible and large enough that you learn from people who have already solved the problem you are facing. Learning, curiosity and honest debate are valued over hierarchy. **Growth & hiring** Physics Wallah hires internships across engineering, data, product, design, marketing, finance and operations, and a meaningful share of its early-career hires convert to full-time offers. All openings are published on the company's official careers page, and applications for this role are submitted directly to Physics Wallah there — no middlemen, no aggregators.

  • For system design, use the RESHADED framework: Requirements, Estimation, Storage, High-level design, APIs, Detailed design, Evaluation.
  • Prepare 3–4 STAR stories covering: a challenge you solved, a time you worked in a team, a project you owned end-to-end.
  • After every coding solution, proactively state the time and space complexity — interviewers expect it.
  • Study common CS fundamentals: process vs thread, TCP vs UDP, REST vs GraphQL, SQL indexing, CAP theorem.
