Final answer:
The correct form of the verb is habrás llegado.
Step-by-step explanation:
The correct form of the verb is habrás llegado.
When using the verb haber in the future perfect tense, you must match the verb form with the subject pronoun. In this case, the subject pronoun is tú, so the correct verb form is habrás llegado.
For example, if the sentence was '¿Yo llegado cuando nosotros tenemos la entrevista?', the correct verb form would be habré llegado.
