I spent 1 and half years at Clinical Laboratories and it was the best job I've had. The bosses are so down-to-earth and very flexible.
I learned a lot in the billing department in the short time I was there. (Insurance info, FIN system, how to handle cash and check payment securely, 10-key numeric skills, etc) I was also able to cross-train into other areas of our deparment. (claim payments and denials)
The other girls in our billing team were great and very helpful in training me and easy to get along with.
To me, the hardest part was being to post payments and file them by deadline (End of month and end of year) but working as a team, it was great to see everyone work together to meet these deadlines which made it the most enjoyable part of working at Clinical Labs.
