You might consider retesting for a higher score.

I took my test in april and got a call last week to come in and interview so long process

It's a very long drawn out process, I applied on 4/5/15 and just got an email for an invite to interview yesterday 6/1/15. Don't be surprised for the process to take anywhere from 4-8 weeks from start to finish or longer.

Do they email you when they will interview or do they mail you a letter
