Apple Software Engineer interview questions

Frustating experience: got contacted by hiring manager , the recruiter took more than one month to get back, then planned 6 rounds of interview, very less accommodative with change of dates for the interview. Interviewer asked very casual current job related questions, no technical questions regarding DSA or other CS topics, next week recruiter sent rejection stating that my skills not meet the job requirements, if this were the case, why was I contacted at first place. Very bad experience.

felt very professional but somewhat cold, interviewers were polite but didn't make much effort to make feel comfortable or engaged. overall, it seemed more like a one-sided evaluation rather than a two-way conversation
