Apple Software Developer interview questions

On Campus Interview, phone screens from various teams, onsite interview with each team each consisting of 4 technical interviews and a lunch interview. Interviews were specialized to the team rather than general questions.

I was completely disappointed with the interview process. I have 4 years of work experience in backend software systems and Big data. I have interviewed with 4 different teams though I did well in all 4 different team phone interviews, they didn't call me for on site. 1. Some video processing team: one round with recruiter and one round with Hiring manager. He asked very simple questions I have answered all. Even he was happy with the answers. 3 days later I got reject. 2. Apple Mac os: This is the worst ever interview process in my life. 1 recruiter, 1 hiring manager round. Answered all the questions . Got another coding round. It's a leet code hard question. I did well and the ans is also correct. Got one more coding round. 2 coding questions. Did very well. after 3 days I got a reject. Seriously!!!? They can't reject based on my performance. But if they thought I have less experience, they should have known that before and shouldn't have even conducted 3 phone interviews. What a waste of time. 3. App store. 1 hiring manager round. did well and 1 phone interview lasted around 1 hour 15 min though it got scheduled for 1 hour. Did well. After 2 days got a reject. 4. App maps team. 1 coding round. Did well. Got reject in 3 days. Seriously. I have wasted so much energy and time going through this stupid interview process. I had offers from startups. My sincere advice is, If you are ready to waste time on this, then you can go ahead and apply . otherwise please don't. There are so many companies out there.
