When applying to airlines, they’ll expect you to know how to use a glass cockpit (Horizontal Situation Indicator). If you trained in old aircraft like me, chances are that you won’t have any experience flying with an HSI.
To remediate this, you can download a GPS/glass cockpit simulator from the garmin website. More info on the following post: http://www.flightschoollist.com/aviation-gps-simulators.php
