Does anyone know how long it takes to ger hired for the post office as a CCA?

I applied for the CCA a month ago then a week later when I applied, received the Motor vehicle record search and submitted it between the time window it asked to be done by. I just see it says I'm on the pre hire list, but I did good on the assessment and got like a 96. I had applied for Texas City location and even Humble and also Crosby. I understand its a process , but seeing if anyone can give a possible time window on what to expect or the steps it takes.

I'm trying to find work now with the news of my current job shutting down for good in two months.

I've got warehouse and customer service experience and have worked in a lab for two years, but no degree just a high school diploma.
