Key takeaways

  • Prepare for the specific role: the job description tells you what to revise.
  • Know your own projects deeply. Most technical conversations start there.
  • Practise out loud with mock interviews until explaining your thinking feels natural.

Technical interviews can feel intimidating when you do not have work experience to talk about. The good news is that interviewers for fresher roles mostly want to see three things: solid fundamentals, proof that you can build something, and a clear way of thinking and communicating. All three can be prepared.

Understand the interview process

The exact process varies by company, but fresher hiring often includes some combination of these rounds:

  • Online assessment: aptitude, reasoning and sometimes coding or SQL questions.
  • Technical interview(s): fundamentals, problem solving and questions about your projects.
  • Managerial or team-fit round: how you work, learn and handle problems.
  • HR round: background, expectations, location and joining details.

Ask the recruiter what the rounds are. It is a normal question and it helps you prepare for the right things.

Step 1: Read the job description carefully

List every skill and tool mentioned. Mark each one as strong, okay or weak. Your preparation time should go mainly to the must-have skills you marked weak.

Step 2: Revise the fundamentals for your role

RoleData Engineering

Revise first
SQL (joins, aggregations, window functions), Python, data modelling, ETL/ELT concepts, Spark basics

RoleGenerative AI / AI Engineering

Revise first
Python, machine learning basics, how LLMs are used, prompt design, RAG, working with APIs

RoleSoftware Testing

Revise first
SDLC and STLC, test case design, bug life cycle, Selenium basics, API testing, SQL

RoleAll roles

Revise first
OOP concepts, DBMS basics, Git, and basic data structures and problem solving

Step 3: Know your projects inside out

For every project on your resume, be ready to answer:

  • What problem does it solve, and who would use it?
  • Why did you choose this approach and these tools?
  • What exactly did you build, especially in a team project?
  • What was the hardest problem, and how did you solve it?
  • What would you improve with more time?

If you cannot explain a project on your resume, remove it or revise it until you can.

Step 4: Practise problem solving out loud

Interviewers care about how you think, not only the final answer. When solving a problem: repeat the question in your own words, ask clarifying questions, explain a simple approach first, then improve it, and test your answer with an example. Practise this out loud, because thinking silently and speaking your thoughts are different skills.

Step 5: Prepare behavioural answers with STAR

For questions like “Tell me about a time you faced a challenge”, use the STAR method:

  • Situation: the context, briefly.
  • Task: what you needed to achieve.
  • Action: what you specifically did.
  • Result: the outcome and what you learned.

Prepare four or five stories from projects, college, internships or part-time work that you can adapt to different questions.

Practising a technical question out loud and getting feedback on the answer.

Step 6: Do mock interviews

Mock interviews are the fastest way to find gaps. Practise with a mentor or friend who can give honest feedback, and use AI mock interviews to rehearse as often as you like. Record yourself at least once: you will quickly notice filler words, rushed answers or topics you explain poorly.

Step 7: Prepare your own questions

At the end, you will usually be asked if you have questions. Good options: “What would a typical first month look like in this role?”, “What does the team’s tech stack look like?” and “How do you measure success for someone in this position?”

The day before and on the day

  • Re-read the job description and your resume.
  • For online interviews, test your internet, camera, microphone and the meeting link in advance.
  • Keep a copy of your resume, a notebook and a pen nearby.
  • Join or arrive a few minutes early.
  • If you do not know an answer, say so honestly and explain how you would find out.

Common mistakes to avoid

  • Listing tools on your resume that you cannot discuss.
  • Memorising answers word for word instead of understanding concepts.
  • Staying silent while thinking during a problem.
  • Speaking negatively about previous teams, colleges or employers.

Frequently asked questions

How many projects should a fresher have?

Two or three strong, relevant projects that you understand deeply are better than many shallow ones.

What if I freeze during the interview?

Pause, take a breath and restate the question. Talking through a simple first approach usually gets you moving again. Regular mock interviews make freezing much less likely.

Should I send a thank-you note after the interview?

It is optional, but a short, polite message to the recruiter thanking them for their time is a good professional habit.
