Cadence Design Systems Senior Software Developer interview questions

It was a full-day (9-5) interview, which was scheduled after a phone screening. In the first part of the day, the questions were a mix of algorithmic, coding, and problem-solving questions. However, several interviews that happened after lunch were nearly a complete waste of time. Interviewers were mostly unprepared. The hiring manager was extremely nosy about my personal situation (family, etc). After wasting so much of my time they did not bother to send me a formal rejection e-mail.

4 rounds excluding HR discussion. 1st round on phone and 3 onsite. All of the interviewers were nice except for the last one. The last interviewer was rude and unprofessional. The last round of interview started with the statement that my resume is tailored and I don't know what I have written on my resume and this was somehow evaluated without having a word with me and the interviewer was shaking his head and shrugging every time even before I end up answering something. Communications from HR were slow and I had already made my decision before the offer was released.
