BlackBerry Interview Questions & Reviews

Interview Details – Got a phone call from the HR manager & he asked about few stuffs in the resume. He scheduled a technical round on the immediate next day. A senior level engineer called me & asked questions regarding auto-interrupts, external interrupts, SPI, UART & DAC. He also asked some questions in C about linked list & structures. Asked few questions from RTOS, difference between semaphore & mutex, scheduler & stack, frame pointers.

Interview Details – The interview was based only in two questions, and the last question was to give an answer in a concept of mechanical engineering. I guess was not bad for an interview with them. Unfortunately, no answer since then (at least from the company if I was accepted or not), however, the HR said that they choose a candidate and those ones rejected received an email notifying. Email which I never received and thank I wonder to ask, if not I'll be still waiting for a response

Interview Details – Sent resume on campus job fair. Got a email notification for a 30-minutes phone interview 3 weeks after that job fair. The phone interview has nothing to do with technical problems. The interviewer first introduce the basic information of their company and their development teams. Then he just asked several questions about the resume. Then, he asked about the biggest coding project you did before.

Interview Details – First did a phone interview, which was half technical half behavioral. Was called back to do an inperson interview which lasted most of the day. I was interviewed by different people, in different areas of the company. The first interview was technical while the others were more behavioral, to see if I would fit the office's environment.

Interview Details – Initial email from recruiter saying I had been selected and verified a time to speak with the hiring manager. Meeting was about 2.5 weeks after this email. Actual interview was mostly manager explaining the position and whats expected from this individual. It was not a standard interview from my experience, none of the nonsense SAW or situation questions on the first interview. Those I spoke with were nice, although HR appeared to be uninformed as much was left up to the manager. No discussion of salary, which can be a waste of everyone's time if its too low.

Interview Details – RIM job fair. only 30 minutes.

Interview Details – I have applied for the software engineer internship position on the website of RIM, after about 3 weeks, the recruiter contacted me and said that one group wants to interview with me. The phone interview is scheduled about 1 week later.
