I applied online. A few days later I was called for more information. They sent a screening questionnaire to fill out. A couple weeks after that I had a call with the hiring manager and I was recommended for a panel interview.
The interview was done over zoom with two of the cyber managers that were hiring for positions on their teams. The interview consisted of them asking about past work experience listed on my resume, several conceptual questions about networks, C/C++ programming, reverse engineering tools, etc. They also brought up some C and C++ programs and asked some code review type questions.
Overall very pleasant interviewers who made me feel at ease throughout the process.
