Pretty much everything here is on point: Basic phone interview to make sure you are competent, a quiz that tests if you have basic knowledge of US Geography, and an in-person interview with the hiring manager/SOL.
The in-person interview was really the toughest part. Mostly you just need to be confident, and show that you are 'money hungry'.
Beyond that, the job is decent for the first 6 months while you are training, and then they put you into 'proving grounds' where it is the 'smile and dial' philosophy while they also expect you to build trust with companies that have probably been called 50 times by other people in TQL that week.
The upside is they are massively transparent, you can see in daily/weekly reports who in the company is doing the best and compete within your own group as well. You can also see that they lose as many people as they hire every month (and it's more than most small companies have total employees) and they require that 'churn and burn' to fuel their 'LAE - LAET' mentor training program. You can also see that the largest portion of their LAEs will generate enough revenue to get just over the base if they even get a commission (it is base or commission, they do not combine, though they like to make it sound like it is at first).
So unless you actually are happy with the base pay, don't bother, but also don't tell your interviewer that, because he wants to hear that you want to be a million dollar broker.
TQL is also viewed negatively by a lot of trucking companies because 'you build your own book of business' and 'run it like you want' employees have a tendency to treat truckers poorly. And there are times where a trucking company may make an attempt to hold your freight hostage, not show up at all, show up late and cost you a customer, showing just how little control you have over your job.
I'd say if you bothered to come to Glassdoor before the interview and aren't a recent college grad with no experience, you probably shouldn't waste your time.
