ServiceNow Interview Questions and Answers

Assuming the database name of the ServiceType field is "u_servicetype", this should work: var gr = new GlideRecord('sys_user');
gr.get(g_user.userID);
var svcType = gr.u_serviceType;

Note that this might have a slight UI delay since gr.get is doing synchronous AJAX call. You can do it asynchronously with a gr.query and a callback function, as:

var gr = new GlideRecord('sys_user');
gr.addQuery('sys_id',g_user.userID);
gr.query(function(user){
if(user.u_servicetype=="CMS"){
   return;
} else {
   // all the rest of your code...
}
});

Record Matching- This feature enables the executives to determine the rules which are being automatically set on single or multiple values of the fields when predefined conditions are met.

Impersonating a user means a user can temporarily sign in to a network as a different user. If a user has full impersonation permissions he can impersonate all users of that network and can do anything. This feature of Service now is used in testing and helps other users in troubleshooting the problems by logging in to it.

UI Policies are the same as Client Scripts which governs the form and its field behavior. It changes information on a form dynamically and controls flow for tasks. UI policies are used to set mandatory fields.

An inactivity monitor helps in triggering an event for a task that has not been updated in a defined period. And if the task remains inactive for a longer duration then the monitor repeats at regular intervals.
