I was interviewed at Expedia London for an entry level Software Development role.
At first, finished their online assessment with a good score. After 5-6 weeks of the online assessment, I was invited for my final rounds of interviews. I had 3 interviews, 1 Coding Interview, 1 Behavioural Interview and 1 Design Interview with a coding challenge at the end.
Total Coding problems: 3
If you can solve Leetcode easy-medium problems, you can solve anything. I cannot reveal confidential coding problems that were asked in the interviews, but I can say I was asked Leetcode Easy-Level problems. Design interview was more focussed on Object Oriented Programming. Behavioural interview is pretty standard.
My tips to the candidates. Clearly communicate well with the interviewer. The whole purpose of the coding interview was to come to the most optimal solution. But that is okay even if your solution is not the best. Just walkthrough the interviewer clearly until the end. Make sure you review Object Oriented Principles.
