The new pilots most likely to have a problem getting 'Command' hours, (PIC), are those that pay their way through flight school and type rating straight into the right hand seat, (FO), of a transport jet.
If a new pilot, having obtained his CPL, is able to get a single crew job on light aircraft and build up, say, 1500 to 2000 PIC that will probably be enough to satisfy all licence requirements. Unfortunately, in this day and age, you may still need to buy a jet rating to get taken on by the airlines unless your lucky and find an employer that will pay for your rating, such employers will probably require a Return of Service of between three and five years. Command will come when you meet the experience and qualifications requirements of your employer and it is your turn, i.e. you have seniority.
