MongoDB Associate Technical Service Engineer interview questions

In a communication with recruiter via LinkedIn . Recruiter team was good and communicating but I feel as JD specific they didn't specify the role after facing interview with hiring manager I came to know it's all about Support like in case anyone who is using MongoDB product faces some Issue they will contact you and you have to support them till the issue resolved and my interest went like half after listening description of job as I was looking for something mix of development and operations or opportunity in cloud computing but roles doesn't match my expectations . Plus recruitment team will present this as a fancy job to you .Incase I will get this opportunity I m not going to join this role. They said that it's a database product but not a single questions was related to database and it feels like all stuff of system admin (linux) . Now coming to question as I said all OS stuff What is TCP/IP , UDP and what is zombie and orphans process. What is memory swap what is VM . What issue u face in day today activities all related to OS and networking .
