Did they screw up my quartzite countertop seam?

Just had my quartzite countertop installed yesterday. I waited overnight to really get a close look at the workmanship. I have one seam that connects halfway through my cooktop and it feels really rough at the bottom end. Almost like I could snag a rag or sponge on it. Does this look right? It feels like it needs to be filed down. Any help or advice is much appreciated. We're newbies at home improvement stuff.
