How to get hired
Read the skills line before the title. A "Full Stack Developer" post in India almost always belongs to one of three pairings, and each comes from a different kind of employer.
Java full stack (Angular or React with Spring Boot)
The services-firm and bank version. HCLTech, Wipro, UST, Xoriant, Deloitte and bank technology centres such as Citi hire "Java Full Stack Developers" for enterprise portals: Angular (sometimes React) on the front, Spring Boot microservices behind, Oracle or PostgreSQL underneath. The interview is two halves stitched together: a core Java and Spring round (see the Java guide) and an Angular round on components, services, RxJS observables, change detection, routing guards and reactive forms. Many of these openings are contract-to-hire through staffing firms; read contract jobs through agencies.
MERN and its cousins (React with Node.js)
The startup and SaaS version: React or Next.js on the front, Node.js with Express or NestJS behind, MongoDB or PostgreSQL, deployed on AWS or Vercel. These teams are small, so "full stack" means you take a feature from database table to button, including the deploy. Interviews include a practical round: add a feature to a starter repo in two to three hours, or a take-home. The frontend guide covers the language round they start with.
.NET full stack (Angular with ASP.NET Core)
The Microsoft-shop version, common in healthcare, labs, insurance and manufacturing GCCs, with Azure and SQL Server. See the .NET guide for the C# side.
What every full stack interview checks
Beyond each half, interviewers look for whether you understand the joins between them, because that is the part only a full stack developer owns:
- How the browser talks to your API: CORS, cookies vs tokens, where you store a JWT and why it matters
- Authentication end to end: login, session or token refresh, logout, and protecting routes on both sides
- Pagination, filtering and sorting done in the API and the database, not by loading everything into the browser
- File uploads, and where files should actually live (object storage, not your server's disk)
- The common security holes in the OWASP Top 10: SQL injection, XSS, broken access control
- Deploying it: environment variables, a build pipeline, logs you can read when production breaks
A favourite question: "A page takes eight seconds to load. Walk me through finding out why." Good answers go from the browser's network tab to the API timings to the database query plan, in that order.
Avoiding the shallow-generalist trap
The risk of full stack is being average at both ends. Interviewers for senior roles ask "which side are you stronger on?" and expect a straight answer. Go deep on one side, usually backend for Java and .NET pairings and frontend for MERN, and be competent on the other.
First titles and the climb
Freshers rarely get the full stack title at large firms; they join as Software Engineer and get put on a full stack project. Startups do hire junior full stack developers. Lateral titles read Full Stack Developer, Full Stack Engineer, Java Full Stack Developer, Senior Software Engineer – Fullstack and Lead Full Stack Engineer.
What the work is like
At a services firm, a full stack developer often works on one side for months at a time, depending on the sprint. At a startup, you switch sides several times a day, and you are the one called when the feature breaks, wherever it breaks.
Full stack experience is a strong base for technical lead, engineering manager and founding-engineer roles, because those jobs need someone who sees the whole system. Pay jumps when you add cloud and system design to the stack, not when you add a third framework.
