2 step process, one Skype ( coding) and one on-site. Skype interview was alright, basic coding stuff to see if you know how to code. On-site interview consisted of 30 minute presentation and 5 different interviews. Interviews were brutal. They expect you to basically know everything. One behavioral and 4 technical. The 4 technical interviews consisted of the following: going through schematic and data sheets, fixing a code, and 2 op amps heavy interview. Each interview get a bit condensing because I wouldn’t get the answer correct and I can tell the disappointment. Really glad I didn’t get an offer though. As I was on site, I got a really bad vibe of the entire place. I felt like Keysight is an older company where you go after having experience, it isn’t for a fresh grad( as I am). Overall, the technical interviews were tough and if you aren’t really smart, it will feel as they are looking down on you. HR contacted me days later for reimbursement fees and 2 months later, no reimbursement and HR’s email doesn’t exist anymore.

It was a one hour interview with half and half behavioral and technical. In general, the questions weren't hard, but I put "difficult" for interview difficulty because they showed me a graph and asked how I would write a program that calculates its cutoff frequency. I didn't have to write the code, but basically talk them through my approach. Also, they asked a lot of core concepts of CS questions.
