How to Prepare for Your Technical Interview
Technical Interview Preparation Guide
It can be quite challenging to prepare for a technical interview, especially if it is your first time or you’re aiming for a top role. Regardless of being a fresher or an experienced professional, success requires proper use of time and energy. This guide offers tips and strategies for technical interviews across fields like software and mechanical engineering.
Understanding the Technical Interview
Technical interviews evaluate your problem-solving skills, theoretical knowledge, and practical application. Expect logical, theoretical, and hands-on problem-solving questions relevant to the job.
Preparation Focus: Assessing Technical Skills
1. Understand the Job Requirements
Know what the job entails. Understand the required technical skills and focus your practice on them.
2. Brush Up on Fundamentals
Review basics of your field:
- Software Engineers: Data structures, algorithms, system design, and programming.
- Mechanical Engineers: Thermodynamics, fluid mechanics, mechanical design.
3. Practice Coding and Problem-Solving
Use platforms like LeetCode, HackerRank, or CodeSignal. Focus on:
- Arrays and Strings
- Linked Lists
- Stacks and Queues
- Trees and Graphs
- Dynamic Programming
4. Study Technical Interview Questions
Common questions:
- Software: Stack vs heap, reverse linked list, normalization in databases.
- Mechanical: 2nd law of thermodynamics, 4-stroke engine working, stress-strain evaluation.
5. Build and Review Projects
Work on relevant projects. Be ready to explain your contributions and outcomes during interviews.
6. Mock Interviews
Practice through mock sessions with friends, mentors, or platforms like Pramp or Interviewing.io.
Industry-Specific Hacks
Software Engineering
- Master a core programming language.
- Understand system design principles.
- Practice LeetCode Medium/Hard problems.
Mechanical Engineering
