Freshers are usually tested on core Java fundamentals — OOP concepts (inheritance, polymorphism, abstraction, encapsulation), String handling, collections such as ArrayList and HashMap, exception handling, and basic multithreading. Classic questions include "What is the difference between JDK, JRE and JVM?", "Why is Java platform independent?", and simple programs like reversing a string or finding a factorial. Be ready to explain at least one project end to end, because interviewers almost always ask freshers to walk through what they have built.

At the experienced level, depth matters more than definitions. Expect HashMap internals, ConcurrentHashMap, the JVM memory model and garbage collection, multithreading and concurrency, design patterns, Spring and Hibernate internals, microservices, and SQL. Whether you have 3, 5, or 10 years of experience, pair every answer with a real example from your projects, and be ready for system design and scenario-based questions as seniority increases.

Coding rounds usually include string manipulation (reverse, anagram, first non-repeating character), array problems (two sum, second largest, rotate array), recursion (Fibonacci, factorial), sorting and searching, and Java 8 stream questions like finding duplicates or the highest salary from a list. Practise writing compilable code by hand or on a shared editor, and always explain your logic and time complexity out loud — interviewers judge your approach as much as your final answer.

Follow this order: HTML and CSS (flexbox, grid, responsive design), then solid JavaScript fundamentals, then Git and GitHub, and finally a framework — React is the safest choice for jobs in India. Build three or four deployed portfolio projects instead of ten unfinished ones, learn browser DevTools and how to consume APIs, and treat the frontend developer roadmap 2026 as a month-by-month sequence rather than a checklist you rush through in a week.

Popular free options include roadmap.sh and community-maintained GitHub repos, but many free PDFs are just link dumps. Pick one that includes project milestones, interview preparation, and updated tooling — not an outdated list. A roadmap PDF works best when you track your progress week by week instead of skimming it once.

Keep it to one page, put education and projects above any experience section, and add internships, certifications, and hackathons to fill the gap. Quantify project outcomes (users served, accuracy improved, load time reduced), list only skills you can defend in an interview, and use a clean single-column, ATS-friendly layout tailored to each job description.

Replace responsibility lines with achievement lines — "migrated services that cut deployment time by 40%" beats "responsible for deployments". Limit the resume to two pages, give the last three roles the most detail, mirror keywords from the job description so it clears ATS screening, cut technologies from a decade ago, and highlight mentoring or ownership to demonstrate seniority.

Highlight coursework, personal and academic projects with GitHub or live-demo links, hackathons, and relevant skills at the top. Mention your availability (duration, full-time or part-time) because recruiters filter on it, keep it to one page, and apply early — internship shortlists fill months before deadlines, especially at startups and through off-campus drives.

A resume template is a preformatted layout with fixed sections — header, summary, skills, experience, education — so you only fill in the content. It saves time and keeps formatting consistent, but heavily designed templates with tables, text boxes, and graphics often fail ATS parsing. A simple, single-column template with standard section headings is the safest choice.

Open Word, go to File → New, and search "resume" to load the built-in templates. Pick a single-column design, replace every placeholder with your real content, keep one font throughout, and avoid text boxes and icons that applicant tracking systems cannot read. Export the final file as a PDF (unless the job portal asks for .docx) and name it clearly, like "FirstName_LastName_Resume.pdf".

Build two or three small projects first — that counts as experience for internship applications. Apply through off-campus drives, LinkedIn, Naukri, and company career pages, and start two to three months early because shortlists close fast. Send short, specific messages to recruiters and alumni with your resume and a one-line pitch, and ask seniors for referrals — one solid project link plus a referral gets more interviews than a hundred blind applications.

Find employees at the target company on LinkedIn — alumni from your college are the warmest entry point. Engage with their posts first, then send a short, specific message with the exact role ID, your resume, and one line on why you fit. Never mass-spam "please refer me" requests, always personalize, and send a thank-you note afterwards. In India's IT hiring, a referral mainly gets your resume seen — you still have to clear the interview on your own.
