The OJT company ask me to do 6 months internship instead of 3, Is that possible?
I recommend considering a maximum of a 4-month internship. A 6-month commitment is quite long, especially without any guarantee of transitioning into a permanent role. You might risk losing momentum and losing sight of your ultimate goal of securing a full-time job.
However, if you're set on taking the 6-month OJT with a big company because it’s a great opportunity, I understand. Just keep in mind:
Excelerate/Pilihan Wibawa will only cover your salary for the first 3 month of the program. You'll need to negotiate your pay for the remaining 3 months with them. You must still adhere to the program's timeline, meaning you need to secure a full-time job before the date mentioned in your contract
