When preparing for a tech interview, it’s important to cover various areas, including technical skills, problem-solving, system design, behavioral insights, and industry knowledge. Below is a comprehensive guide to help you ace your next tech interview.
1. Coding and Programming Questions
Coding challenges are at the heart of most tech interviews. You’ll likely be asked to solve algorithmic problems or demonstrate your understanding of data structures. Here are some examples:
- Data Structures:
- Implement a function to reverse a linked list.
- Write code to find the maximum depth of a binary tree.
- Explain and implement a hash map.
- Algorithms:
- Perform a binary search on a sorted array.
- Write a function to sort an array using quicksort or mergesort.
- Given a string, find the first non-repeating character.
- Problem Solving:
- Find the longest palindrome in a string.
- Determine if two strings are anagrams.
- Write a function to detect a cycle in a graph.
