Here are some common coding interview questions and answers:
String-based questions: How to find the first unrepeated character in a string, how to determine if two strings are anagrams, or how to convert a numeric string to an integer
Array-based questions: How to find the maximum element in an array, how to sort an array of integers in ascending order, or how to remove duplicates from an array
Linked list-based questions: How to find the middle element of a linked list, how to remove a loop in a linked list, or how to merge two sorted linked lists
General programming questions: How to write a piece of code from requirements to delivery, how to debug a program while it's being used, or how to stay up-to-date with the latest technology developments
Data structure questions: What is a tree in data structure, or what is a binary tree
Palindrome questions: How to determine if a string is a palindrome
In addition to the technical aspects of coding, interviewers may also assess an applicant's communication skills. They may ask how well the applicant explains complex concepts or the method they used in a live coding exercise.
