Waiting 2 minutes for unit tests of the relevant module is not very long - using bazel helps to only run the relevant unit tests, not the full suite.

It really depends on what you are doing. Sometimes I am not building in a day, just designing and thinking by editing. Sometimes I am refactoring for hours without building. But sometimes I am rebuilding every 10 seconds or so.
