I was wondering if it's possible to configure the behavior of tab completion in the mongo shell? The two behaviors I've seen are:
I personally much prefer the first option. I've seen both behaviors on different environments (all with mongo version 2 and up), and can't figure out whether it's configurable or caused by the environment.

Note: Instead of typing the exit command, an alternative way to close the shell is to press CTRL + C instead. Now try reconnecting the MongoDB shell to the database server, but this time provide a username and password to properly authenticate into your MongoDB instance.
Connect to MongoDB database You can start the server in CMD using the following command. Then type mongo command to run the shell. Now you are in the Mongo shell. If you want, you can run the mongo and mongod without the command prompt.
To list all collections in Mongo shell, you can use the function getCollectionNames().
The mongo shell is an interactive JavaScript interface to MongoDB. You can use the mongo shell to query and update data as well as perform administrative operations.
The mongo shell autocompletion behaviour definitely isn't a configurable option. There are some differences in shell editing behaviour depending on the version of MongoDB you are using.
These differences extend beyond autocompletion to line editing, history, and keyboard shortcuts .. but to confirm your autocompletion observations:
It is certainly possible to use a mongo shell version which is different than your MongoDB server version if you prefer a given shell's behaviour. To take advantage of all server features and documented shell helpers you generally need a mongo shell version which is the same or newer major version as compared to the mongod version.
