Depends on the role.

Some "DevOps" are "SysAdmin with a little development" while others are "Development with a little SysAdmin."

But for either you need to likely be comfortable setting up a WAMP or LAMP environment (and similar popular software, Nginx, IIS, postgresql, Cassandra, memcached, etc). along with decent familiarisation in scripting both (e.g. bash + PowerShell) and a good solid grasp in whatever languages they use (e.g. Java, Python, etc).

Overall most DevOps positions are unpaid for the qualifications they require and expect unreasonable levels of knowledge. There are people who could do DevOps but they have enough experience now so that they'd never take the salaries offered for the majority of DevOps roles (i.e. you rarely see medium-large companies after DevOps, they prefer two specialists and pay each more).

I'd definitely be careful with DevOps, unless it is a sub-10 person business they're likely just trying to cheap out on either development or systems support. In either case it speaks badly of a company.
