Tresys interview questions

Phone interview then in person interview with a software engineer, upper level product manager, and VP. Lots of algorithmic questions over the phone as well as general computer science questions and why I was interested. In person, there was an hour or so of writing pseudocode in response to questions, then an examination of my general technical knowledge, followed by a discussion of cybersecurity and its salience in the modern world. Everyone was very polite and it was a pleasant experience.

Submitted resume & cover letter then had a roughly 1 hour phone interview which was a mixture of questions regarding algorithms and computer science concepts with one of their software engineers, as well as personal and career questions with some higher level management. Shortly thereafter I was invited to headquarters for a longer, tripartite interview, with more extensive coding questions (on paper), then more general computer science questions, and finally an interview with one of the founders.
