Congratulations on your interview! Since you sent a thank you email right after the interview occurred, I don't think it's necessary to send a thank you note via mail as well. At this point, it will seem a little delayed and would be redundant to the email you already sent. It's always difficult waiting for an offer decision following an interview, especially if it's 2 weeks! I would recommend trying to remain patient and wait until after the deadline they gave you before following up again. If you don't hear from them when they promised, I would definitely follow-up with a second thank you email and explain you're still very interested in the position and company, and you're reaching out to see if a decision has been made yet.
