Inquiring about salary expectations will likely lead to an offer that does not exceed 30%, with 12% as a variable amount allocated for a performance bonus, which you may never receive, based on the rationale that your experience is not relevant, despite having a background in a related field such as voice processing. Additionally, do not anticipate clear job descriptions, as the company's approach is broad and diplomatic, reflecting a lack of transparency.

Interview Preparation Tips
Schedule one on ones so he can start the day by shouting at people.
Belittling
Humiliating
Crushing people's confidence
Every year, he goes on a rampage so he can replace his entire team.This is a routine toxic practice he religiously follows regardless of the work that you do.
He has a step by plan, follows the exact same script regardless of what you do and don't do. For example, a co-worker who has a MA in linguistics was told to improve her English. This is hilarious and ironic at the same time. Another Co worker who has trained at least 15000 associates across locations in the last 2 decades. And suddenly the organization realizes that she missed a full stop. And she gets fired for a full stop, a comma and a colon.
Ridiculous, horrible, pathetic are just a few small words for this place. MY SERIOUS ADVISE, DON'T JOIN. SIT AT HOME BUT NEVER JOIN ADP.
