Intercontinental Exchange Sr. Software Engineer interview questions

There are 3 rounds. Two technical and one managerial, followed by HR discussion. The technical interviewers were nice. Questions were coding and java concepts both. However, HR is extremely unprofessional. They matched the initial expectation first and then doubled down on it while actually releasing the offer letter. Don't interview candidates if this is what you have to do. What's the point of asking the expected CTC if you don't want to match it in the first place. Very very unprofessional.
