Applied on company website. After 1 month requiter contacted with me trying to schedule initial interview regards completely different positions. When I mentioned that I didn't applied to these positions, she said that I applied to DevOps Chief Engineer via 3rd party website so I'm not in their system. I provided screenshot from Leidos Career portal as a proof that all what I made was correct and I applied directly to Leidos. At that point, I decided to not go further as this hiring process looks like a joke.
