First and foremost: this is a collections firm that primarily deals in debt. At almost every level and any position you will be witness to an intense degree of despair and misery. You will likely be witness to obscene balances that debtors have no hope of paying back. BYL is a very ethical company and conducts itself with utmost respect towards the law and accommodating debtors as compassionately as possible, but it's still a business that can weigh heavily on your conscience. This is a major contributor to early-onset burnout for a lot of people regardless of position. You have to be kind of hardened to make it in BYL long-term.
Second, this is a company founded by an accountant. Founder and CEO Jeff Heft is a lovely man and I've never had an interpersonal problem with him. So I mean all due respect when I say that Jeff has one of the most serious cases of "accountant brain" I've ever encountered. Every single thing has to be quantified, recorded, evaluated, and audited. There is no room for abstraction or ambiguity, everything has to be noted down to the last decimal of a percentile. Jeff and his team evaluate everything through the numbers. This is good for a lot of people, but it can be extremely grating and irritating for other people, and the constant tracking and measuring of every aspect of your day can be a major contributor to burnout.
Finally, BYL is a small company, and as with most small companies, there isn't too much room for long-term upwards mobility. You'll build a lot of skills and maybe some connections (knowing HIPAA and related protocols is surprisingly valuable), but it doesn't have too many openings to grow your career position-wise.
On a final personal note, all inter-office communication is handled through Microsoft Teams. It's bad, and I don't like it.
