BMO Financial Group Devops Engineer interview questions

Just had one technical round. Focus was more on technical side rather than behavior. I was able to answer most of the questions but I was lacking previous relevant experience in the same field

1st Round of interview was with COE. No company introduction given, directly jumped to technical questions - very serious, straight to the point, abrupt random questions. Example: What is the difference between Continuous delivery and continuous deployment? TO what is 'isof' (i as in ice cream) have you used this command in Linux ? ( not 'LSOF' (list of) Why should it matter, if I am wearing a headphone/earphone/or am on speaker really !!
