The phone screen wasn't very fun or challenging. Mostly trivia questions (i.e. What is a css-sprite?) All the questions were the kind of questions you could google and easily find as the first result, no actual problem-solving required. The only algorithm question was "what is the best case time complexity to sum a list of numbers." The coding test was to build a connect four app using html/css/js. No grading criteria was given, nor did I receive any feedback besides the rejection.

Write a function which will determine if a given string is palindrome or not. bool ispalindrome(string input); I was able to complete the problem and even the interviewer seemed satisfied with the solution. Test Cases: "racecar" => true "!!a!" => true "abc" => false "a" => true "A Man, A Plan, A Canal – Panama!" => true
Create (describe) function Count number of "1" bits in binary representation of a positive integer

All questions were lc mediums, mainly on data structures and algorithms
oops,spring,spring boot
"Have you worked with Java?" "What is polymorphism?" "What is an interface in OOP?" "Can you explain a LEFT JOIN in SQL?" "How do you secure an endpoint on the backend?" And then there was just conversional questions about React, like React life cycle, Redux, Promise and etc.
