There are basically 4 rounds, 2 technical, 1 managerial, 1HR.
The technical interview will focus more on your relevant work experience in DevOps + The requirement that company needs. The interview lasted for more then a hour. There is no guarantee that if you clear technical round you'll be in.
Managerial rounds do play a vital role, needs to be taken seriously. This is where you're judged & weighted on various aspects. Once you're through this, you're all good.
HR round, more just like the package discussion. Nothing else to add here.
