I applied online. I interviewed at Matasano Security
Interview
The entire process took around 5 weeks.
I applied through their careers website. I had an inital phone screening where the person sopke about the company and the roles i need to perform as an intern. then he asked me few technical questions to test my knowledge on web security. Then he gave a website and asked to do a pen test and write a report for the same. They scheduled two phone interviews in a gap of one week.
Both the persons asked questoins completely on web security and software security. The first interview lasted for an hours time and second was over by 30 min. The first person gave a scneario and asked entire questions from it. At last they never responded back even after repeated emails
Interview questions [4]
Question 1
explain XSS, CSRF, SQL injection and how will you mitigate it
The process took 4 weeks. I interviewed at Matasano Security in Sept 2011
Interview
Interviewer asked some questions about background, past programming experience, why I was interested in the job, etc. Simple stuff. Also asked how a stack overflow works and how a heap overflow works. I got the impression that the questions they ask depend on your background. Later, the interviewer sent me a link to a website (via email) and then told me to find as much wrong with it as I could (security speaking). After that, the interviewer introduced me to would-be boss, who called and we talked on the phone. Pretty much the same as the previous interview.
