ee steps follow aithe meeru technical interview easy ga clear cheyochu.

Step 1: Understand the Interview Process

Most coding interviews Below structure ni follow avutai:

1.Technical Screening: A coding challenge or online test.

2.Technical Interview (DSA Round): A live problem-solving session with an engineer.

3.System Design Interview (For Experienced Roles): Designing scalable applications.

4.Behavioral Interview: Evaluating soft skills, teamwork, and problem-solving approach./p>

5.Final HR Round: Salary discussions and cultural fit assessment.

Step 2: Master Data Structures & Algorithms (DSA)

Step - 3: Develop a Problem-Solving Strategy

Follow the FAANG-Style Problem-Solving Approach:

1.Understand the problem completely → Ask clarifying questions.
2.Plan your approach → Think out loud and discuss different solutions.
3.Optimize before coding → Choose the most efficient solution.
4.Write clean, structured code → Use meaningful variable names.
5.Analyze time & space complexity → Justify your approach.
6.Test with edge cases → Handle all possible inputs.

Step - 4: Mock Interviews & Real-World Practice

1.Practice coding in a real interview environment (LeetCode, Pramp, Interviewing.io).
2.Time yourself while solving problems to simulate real conditions.
3.Participate in coding competitions (CodeChef, AtCoder, TopCoder).
4.Engage in peer mock interviews with friends or mentors.

Step - 5:Master System Design (For Advanced Roles)

If you’re interviewing for mid-level or senior positions, System Design questions are crucial.

Key Concepts:
1.Scalability & Load Balancing
2.Database Sharding & Indexing
3.Caching Strategies (Redis, Memcached)
4.Microservices & APIs
5.CAP Theorem, Event-Driven Architecture

Step - 6: Behavioral Interview Preparation

Common Questions:.

1.Tell me about yourself.
2.Describe a time when you faced a challenging problem.
3.Explain a time you disagreed with a team member and how you handled it.
4.Why do you want to work at [Company Name]?

Practice mock behavioral interviews using platforms like InterviewBuddy or Pramp.
