I applied online. The process took 2 weeks. I interviewed at Qualcomm (San Diego, CA) in May 2012
Interview
I had a phone screen interview which lasted 45 minutes. Answered many tech questions. Was emailed a problem and asked to send back an implementation of the solution during the phone screen. Needed to be in front of a workstation during the phone screen.
The onsite interview is as follows: 6 interviewers in all: 2 managers, 4 peers. Mostly technical questions on communication theories, embedded systems and SW data structure questions. Worked thru some problem solutions on the white board. Some brain teasers.
Interview questions [1]
Question 1
Find a pattern in a string w/o using the language library.
Good. Technical details were discussed clearly, together with my past projects and relevant domain knowledge. The interview was well structured and focused, with questions that allowed me to present my experience, technical background, and problem-solving approach in a coherent way.
Posso dizer que num geral positiva, processo rápido, em uma semana foi realizado. Perguntas de nível médio, bem técnicas mesmo e assertivas. Entrevistadores simpáticos, duração longa de entrevista, mas foram ok.
