I applied through an employee referral. The process took 6 weeks. I interviewed at Tenable (Columbia, MD) in Sept 2017
Interview
6 Interviews including the initial manager screen. Took almost six week. Interviews included several technical interview with multiple engineers in attendance. One included a difficult coding problem that on a scale of 1 to 9 in difficulty, felt like a 8 or 9. Process included a coding challenge take home assignment with a challenging but not overwhelming problem that I put ~ 24 working hours into.
In addition, I was required to provide proof of prior salary by handing over pay stubs. This was very unusual and I have never in the past been asked for this.

I applied online. The process took 4 weeks. I interviewed at Tenable in Jun 2025
Interview
The hiring process consisted of three main stages:
Initial phone screening with HR.
Manager interview: Deep dive into my resume/background and discussion about the project/role.
Technical interview: A live coding session to test practical skills. Overall, a straightforward process.
In an online interview, the shortest path graph question was unclear.
Also the SQL task was unsolvable.
The time given was too short.
The interviewer ignored my solution, and had poor communication.
