This will help you tailor your application and prepare the concepts for the technical interview. Also, it demonstrates your enthusiasm and genuine interest in the company during the interview.
• Review the Basics: Building a solid foundation is essential for a technical interview. Brush up on key topics such as:
  • Programming Languages: Most companies let the candidate choose the language in which they want to code. Be proficient in at least one of the commonly used programming languages such as Python, Java, C++, Javascript, etc. It is recommended to select the language you are confident in instead of choosing what the organization uses.
  • Data Structures and Algorithms: Companies usually conduct Data Structure and Algorithm (DSA) rounds when they hire for a technical position. It helps in assessing the candidate’s ability to analyze and solve complex problems, design efficient software, optimize the use of resources, and create bug-free code. Learn about arrays, linked lists, stacks, queues, trees, graphs, hash tables, sorting algorithms, searching algorithms, dynamic programming, recursion, etc.
  • Complexity Analysis: Complexity analysis refers to determining the difficulty of a problem and the accurate time and space resources required for task execution. There are various complexity analysis tools available that let you compare different algorithms. Big O Notation is one powerful tool that describes time, and space complexity and the performance of an algorithm.
• Practice Coding Problems: Hands-on coding practice is essential for technical interviews. Try solving a variety of coding problems with different difficulty levels and types. You can make use of platforms such as CodeSignal, LeetCode, CodeChef, and many more. Learn to code various problems including Linked List, Dynamic Programming, Array Rotation, Palindrome, Sorting, Binary Search, etc. Practice regularly and time yourself to generate an interview environment. It will help you perform better and solve with speed and accuracy.
• Study System Design: System Design defines the architecture, modules, and interfaces for a system to satisfy specified requirements. It helps create a system that solves a particular problem. A system interview is designed to test the candidate’s real-world problem-solving skills. System design requires knowledge of various fields like networking, databases, and software engineering. You can prepare yourself for system design questions by reading books such as ‘System Design Interview’ by Alex Xu and ‘Designing Data-Intensive Applications by Martin Kleppmann. It helps you understand the core concepts of system design including load balancing, caching, databases, proxies, message queues, and distributed systems. Practice design problems regularly and participate in mock interviews to prepare well for the interview.
• Review Past Interview Questions: Websites like Glassdoor and forums like Reddit often have interview experiences shared by their employees or previous candidates. You can look for the different types of questions that were asked in an interview with a particular company. Some companies have a history of asking certain questions, and reviewing these questions will increase your chances of being selected. You may also connect with peers, and online communities to gather recent interview questions. Group the questions into categories and identify the frequency of them to prioritize your practice. Take notes, choose your approach, and revisit the solution for better performance.
• Mock Interviews: Mock interviews are a crucial part of preparation for a technical interview. Mock interview stimulates real interview conditions. They replicate the pressure and the tense environment of an interview helping you get accustomed to the experience. They reveal areas that need improvements and build confidence, reducing anxiety during the interview. You can make use of online platforms like Interviewing Expert, university career centers, boot camps, forums like Reddit, or professional services for personalized feedback and practice of mock interviews. Regularly participating in mock interviews can significantly increase your chances of success in actual technical interviews.
• Prepare for Behavioral Questions: Technical interviews often include behavioral questions such as ‘Describe a challenging project you worked on’, ‘How do you handle tight deadlines’, ‘How do you work in a team?’ etc. Use the Situation, Task, Action, Result (STAR) method to effectively frame your answer. Behavioral questions are asked to assess the candidate’s soft skills, cultural fit, and ability to navigate real-world challenges beyond their technical expertise. Preparing for behavioral questions is essential for demonstrating that you are a resilient candidate capable of thriving in a dynamic work environment.
• Review Your Projects: Review your past projects before going for a technical interview. Choose projects that are relevant to the job position you are applying for. Highlight the significant impacts they created. Understand the details, tools, and frameworks that you used. Also, talk about the challenges faced and how you overcame them. Quantify the results wherever possible and discuss your learning experiences with the interviewer. Discussing your past projects demonstrates your skills, and shows how you’ve applied your theoretical knowledge in practical applications.
• Brush Up on Communication Skills: Your knowledge is invaluable, but it holds little value if you cannot effectively communicate it during an interview. Practice explaining your solutions and projects clearly and concisely. Avoid using jargon unless necessary and make sure that the interviewer understands your accent and approach.
• Rest and Stay Positive: Rest and get a good night’s sleep before the day of your interview. Confidence and a fresh mind can significantly impact your performance. The interview might exhaust you but be patient and keep making yourself better. Remember, preparation is the key and you have worked hard to get this far.
