It is common practice that people are invited to a hearing for their appeal, for instance when the Court considers that the interview protocol is not sufficient to decide on the case. It is important to carefully read the rejection decision, understand why the asylum claim was rejected and be prepared to explained the reasons why one should be granted asylum. The help of a lawyer or a social worker is critical here.
It is difficult to say if it is a bad sign or not that your hearing invitation came quicker than for others. It depends on the internal organization of the Court and does not necessarily have any meaning.
All the best,
