75% of tech job candidates get rejected within the first 5 minutes of the interview — not because they lack competence, but because they didn't prepare properly. That's what LinkedIn's 2025 survey of 3,000 hiring managers at tech companies revealed.
The good news? Preparing for a tech interview is a learnable skill — just like any programming language. Here are 11 practical tips covering every stage of the interview.
How Do You Prepare Before the Interview?
Solid preparation is what separates candidates who pass first-round screens from those who don't — hiring managers identify prepared candidates within the first few minutes through their specific knowledge of the company and their composed, structured answers to technical questions.
Tip 1: Research the Company Thoroughly
Don't just read the "About Us" page. Dig into:
- The product: Actually try it if possible. Download the app or use the website
- Their tech stack: What languages and frameworks do they use? (Look at past job postings)
- Recent news: New funding? Product launch? Expansion into a new market?
- Company culture: Glassdoor and LinkedIn reveal a lot
According to Glassdoor, candidates who mention specific details about the company during the interview boost their chances by 40%.
Tip 2: Review Technical Fundamentals
Even if you're an expert, review the basics. The most common interview questions aren't about complex technologies — they're about fundamental concepts.
For Frontend Developers:
- Difference between
let,const, andvar - How DOM and Virtual DOM work
- State Management
For Backend Developers:
- Difference between REST and GraphQL
- Database design and relationships
- Security concepts: Authentication vs Authorization
For All Specializations:
- Data Structures: Arrays, HashMaps, Trees
- Algorithms: Sorting, Searching, Big O
- Git: merge vs rebase, branching strategies
Dedicate 30 minutes daily to solving one problem on LeetCode or HackerRank for two weeks before the interview. Start with Easy problems — don't jump to Hard. The goal is building confidence, not solving everything.
How Do You Perform Well During the Interview?
Soft skills matter as much as technical skills during the interview itself — and candidates who explain their thinking clearly, ask clarifying questions, and structure behavioral answers using frameworks consistently outperform technically stronger candidates who communicate poorly. For context on what interviewers value most, read the complete tech career guide.
Tip 3: Think Out Loud While Solving Problems
The biggest mistake in tech interviews: staying silent while thinking. Hiring managers want to hear your thought process, not just see the final answer.
Instead of silence, say:
- "My first instinct is to use a HashMap because..."
- "This solution works but it's O(n²), let me think of a faster approach..."
- "I'm not sure of the best approach here — but I'll start with a simple solution and optimize"
According to HackerRank's 2025 report, 68% of hiring managers prefer a candidate who explains their thinking clearly and reaches a simple solution over one who arrives at the perfect answer in silence.
Tip 4: Ask Clarifying Questions
When you receive a technical problem, don't start solving immediately. Ask:
- "Is the input sorted or random?"
- "What's the expected data size?"
- "Are there memory or time constraints?"
This shows you think like a real engineer — not a student solving homework.
Tip 5: Use the STAR Method for Behavioral Questions
Behavioral questions like "Tell us about a time you faced a technical challenge" need a structured answer. Use the STAR method:
- S (Situation): Describe the context briefly
- T (Task): What was expected of you?
- A (Action): What did you specifically do?
- R (Result): What was the measurable outcome?
Example: "In my graduation project (S), I was tasked with improving page load speed (T). I analyzed performance with Lighthouse and found uncompressed images and render-blocking CSS (A). After optimization, load time dropped from 8 seconds to 2.1 seconds (R)."
Prepare 4-5 STAR stories before the interview covering: solving a technical problem, working in a team, handling time pressure, learning a new technology, and making a mistake and learning from it. These five cover 90% of behavioral questions.
How Do You Answer the Most Common Interview Questions?
Tip 6: "Tell Us About Yourself"
This isn't a request for your resume — it's a chance to introduce yourself in 60-90 seconds. Follow this formula:
Present: "I'm a web developer specializing in React and Node.js" Past: "I worked on 3 real projects in the past year, the latest being..." Future: "I'm looking for a team where I can learn and contribute to building products that serve users"
Tip 7: "Why Do You Want to Work With Us?"
Don't say "because the salary is good" — even if that's the real reason. Connect:
- Your skills with the company's technical challenges
- Your values with the company culture
- Your career goals with available growth opportunities
Tip 8: "What Are Your Weaknesses?"
Don't say "I'm too much of a perfectionist" — that shows a lack of self-awareness. Mention a real weakness with what you're doing to improve it:
"I sometimes spend too much time optimizing code instead of shipping the feature. I've learned to set time limits and launch an MVP first, then improve incrementally."
How Do You Negotiate Salary and Follow Up After the Interview?
Tip 9: Negotiate Your Salary With Confidence
Expected tech salaries in 2026:
| Specialization | Junior ($/year) | Mid-level ($/year) |
|---|---|---|
| Frontend Developer | $50,000-$65,000 | $75,000-$100,000 |
| Backend Developer | $55,000-$70,000 | $85,000-$115,000 |
| Full-Stack | $52,000-$68,000 | $80,000-$110,000 |
| DevOps | $60,000-$75,000 | $95,000-$130,000 |
| Data Engineer | $58,000-$72,000 | $90,000-$125,000 |
Negotiation rules:
- Don't name a number first — ask "What's the budget for this role?"
- If pressed, give a range: "I expect between X and Y based on my experience and market rates"
- Don't accept the first offer immediately — ask for a day to think it over

Tip 10: Send a Thank-You Note
Send a short email within 24 hours after the interview. Thank the interviewer for their time and mention a specific point you discussed. This sets you apart from 90% of candidates who don't do this.
Tip 11: Learn From Rejection
If you don't get the offer — and this is normal and will happen — ask for feedback from the interviewer. Not all companies provide it, but those that do give you golden insights about areas to improve.
Average number of interviews before landing a first tech job: 7-12 interviews. Don't get discouraged by rejection — every interview is practice that improves your performance in the next one.
؟Do I need a university degree to get a tech job?
Not necessarily. According to HackerRank's 2025 survey, 45% of developers at major tech companies don't hold a computer science degree. Companies care more about your ability to code and solve problems than the degree. However, a degree helps pass the initial resume filter — especially at traditional and government organizations.
؟How do I prepare for a tech interview as a beginner with no work experience?
Focus on personal projects. Build 2-3 real projects and put them on GitHub. When the interviewer asks about your experience, talk about these projects in detail — the challenges you faced and how you solved them. Serious personal projects compensate for lack of professional experience at most companies, especially startups.
؟What's the difference between interviewing at a startup vs a big company?
Big companies (Google, Amazon) focus on algorithms and data structures with multiple rounds spanning weeks. Startups focus on practical skills — they may ask you to build a real feature or review existing code. Startup interviews are shorter and more hands-on but expect immediate productivity after hiring.
؟Are remote interviews easier than in-person ones?
Not easier — just different. Remote interviews need extra technical preparation: check your internet speed, test your camera and microphone beforehand, and choose a quiet spot with a clean background. The advantage is you're in your comfortable environment and can keep notes in front of you. The downside is reading body language is harder and you might face technical issues at the worst times.
؟How long should I expect the tech interview process to take?
Interview processes vary significantly by company type. Startups typically complete hiring in 1-2 weeks with 2-3 interview rounds. Mid-size companies run 3-4 rounds over 2-4 weeks. Large companies (Google, Amazon, Microsoft) have 5-7 rounds over 4-8 weeks including a loop with multiple different interviewers. Always ask the recruiter about the timeline at the beginning so you can coordinate other applications and not leave yourself waiting anxiously without context.
؟What should I do if I don't know the answer to a technical question?
Be honest and structured. Say: "I don't know the exact answer, but I can reason through it." Then verbalize your reasoning — what concepts are related, what you would try first, where you'd look to confirm your thinking. Interviewers value intellectual honesty and structured thinking over a confident wrong answer. Fabricating an answer is always worse than admitting uncertainty and demonstrating your reasoning approach.
؟How important is a portfolio compared to a degree on my resume?
A strong portfolio of 3-5 real projects with deployed demos and clean GitHub documentation consistently outperforms a degree alone in screening for technical roles at modern tech companies. The portfolio proves you can ship working software, while a degree proves you completed a curriculum. Both together are optimal, but if you must choose one to invest time in, building projects that solve real problems and demonstrating them publicly creates more interview opportunities than credential accumulation.
؟Can I ask about salary in the first interview round?
Generally no. Salary discussions are appropriate after receiving an offer or when the recruiter raises the topic. In initial interviews, focus entirely on demonstrating your qualifications. Many companies ask candidates what salary they expect before making an offer — when this happens, research the market range first (use Glassdoor, LinkedIn Salary, and Levels.fyi for your role and location), then provide a range with the floor slightly above your minimum acceptable salary. Never give a single number — ranges give you negotiating room.
A tech interview isn't a test of your intelligence — it's a conversation to discover if you and the company are a good fit for each other. Prepare well, be honest, and know that every interview — even the ones where you get rejected — brings you closer to the offer you deserve. Start by solving one problem on LeetCode today. Right now.
