        for (list<RecordType> rts : [SELECT ID, name FROM RecordType WHERE SObjectType = 'Interviewers_Feedback__c' ORDER BY name]) 
        {
            for (RecordType rt : rts) {
                options.add(new SelectOption(rt.ID, rt.Name));
            } 
        }
        return options;

Answer 1

You can use rendered on pageblocksection based on the record type

<apex:pageBlockSection rendered="{!Interviewers_Feedback__c.RecordType.Name== 'opt1'}">

With in single pageblock, you can have 2 apex:pageBlockSection for 2 record types.
