A product-based company, often shortened to PBC, builds and sells its own software or hardware product to customers, instead of building software for other businesses. Hiring usually tests problem solving and data structures more heavily than hiring at service companies does.
In a product company the software is the business. Teams own a product, ship updates and respond to users, so engineers can work on one product for years. In a service-based company, teams build and maintain software for client businesses, so the work depends on client projects.
Hiring is usually tougher on problem solving. Expect an online coding test, several technical rounds on data structures and algorithms, often a round on design or your past projects, and an HR or culture round. Pay and roles vary widely between companies, so compare actual offers and not labels.
To prepare, build strong basics in data structures and algorithms, solve problems regularly on a coding platform, understand your own projects well enough to explain every decision, and revise core subjects such as operating systems, databases and networks.
A product company is not automatically better than a service company. It depends on the team, the learning, the pay and your goals. Many people start in either type and move later.
Before you apply, look at what the product does, who uses it, how large the engineering team is, and how the company treats freshers: training, mentors and the first project. Interview experience posts can help, but treat each one as a single person view.
Startups and product companies often hire off-campus through career pages, referrals and coding challenges, so you may not wait for a campus drive. Build a resume that shows projects and problem solving, and apply early.
PBC stands for product-based company. Its counterpart SBC stands for service-based company.
A product-based company builds its own software or hardware product and earns from selling or running it, for example through subscriptions or usage. It does not mainly build software for other businesses.
A product company builds and owns a product. A service company builds and supports software for client businesses. Hiring tests, work style and growth paths often differ between the two.
Hiring is usually more selective about coding and problem solving, so preparation takes longer. Many freshers still get in with steady practice and strong projects.
Use the language you know best, such as C++, Java or Python, and solve problems in it regularly so that you are fluent under time pressure.
No. Many hire mainly off-campus or from a limited set of colleges. Check which companies visit yours and apply through career pages if they do not.
Product company tests lean on coding. Practise timed papers and then rehearse the interview that follows.
