BlackBerry Software Engineer interview questions

the phone interview is quite straightforward, the HR recruiter went through the resume, my project experiences and skills. Then I got a setup for onsite interview one day later. The onsite interview is quite technical. A team manager and team member went through my project experience first, with details on some technique implementations. Then they asked me some oop, algorithm and low level C programming questions. I answered all of them. The interviewers are quite friendly and easy to help. I got the offer two days later and asked for background checking information.

Traveled to Ottawan, ON for the interview. Conducted a 1:1 interview with a senior developer that lasted for approximately 30 minutes. The interviewer wasn't friendly at all, so it made the interview experience a sour one. He led me into the room and started by asking my previous work experience and then follow up with an algorithm problem, and was then followed by straight forward general questions regarding JAVA.
