Netskope Senior Staff Software Development Engineer In Test interview questions

I had 2 technical interviews with Netskope Team with no interaction with their HR team, interview scheduled just by sending emails, first was completely coding round and second was coding round with multiple QA questions, even after performing well they rejected just because I was not able to write Unix or kubernetes commands with correct syntax, The interviews themselves might not be knowing all proper syntax, totally waste of time as even if you solve coding challenges but not able to write anything as per their expection they will reject you saying it's Senior level position
