no response after interview from The trade desk

a after 2 prior interviews and a final onsite interview with the trade desk i thought my interview went well. after i sent a thank you email which recruiter confirmed they recieved the email and distributed it to everyone who i interviewed with. after about a week or so i emailed asking when i should expect to hear a response. i never heard back so about a week or 2 after that i emailed again said im still very interested. by now ive sent 2 to three emails with no response and i dont want to get annoying either. is this normal for TTD im assuming this is not a good sign or is this some test they play on candidates? #thetradedesk
