Let's start with business ethics. In B2B relationships Trinity has acted highly unprofessional. On multiple occasions they refuse to pay other companies for their work. Instead, they wait until there is a lawsuit. Once the lawsuit begins, they'll often then settle on paying a lower amount then originally agreed upon. This is Trinity 101 how to handle other companies. They'll also do things like sharing email accounts to avoid paying for more subscriptions services even after being directly told that it's against their agreement with the other company. If you're a company doing any form of business with Trinity, they will find a way to exploit your services/product.
BT Dev team. Recently, they hired a CIO to take over technology. Upon being hired, this person belittled every person in the department and then hired family members and friends into high ranking positions. These friends and family members are extremely unqualified. This has lead to a high turnover rate. Multiple new hires only worked for a few weeks before walking out of the office and quitting.
Do not fall for any propaganda the BT Dev feeds you during an interview. Working at this company will be miserable and unproductive.
