This question still really needs a MWE to be absolutely sure what is going on, but here at least is an example that gives the output you want.
I have used the addendum field for Interview mit Daniel Grieder, CEO von Tommy Hilfiger because this is the only suitable field that will be printed after the url field in the standard styles.
Note: You have spelt Hilfiger wrong in your screenshot.
\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage{csquotes}
\usepackage[style=authoryear]{biblatex}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@online{Pittroff2015,
author = {Pittroff, Uschka and Grieder, Daniel},
date = {2015},
url = {http://www.manager-magazin.de/lifestyle/mode/mode-tommy-hilfiger-stellt-auf-digitalen-showroom-um-a-1014348.html},
addendum = {Interview mit Daniel Grieder, CEO von Tommy Hilfiger}
}
\end{filecontents}
\addbibresource{\jobname.bib}
\pagestyle{empty}
\urlstyle{same}
\DeclareFieldFormat{url}{\url{#1}}
\begin{document}
\nocite{*}
\printbibliography
\end{document}

biblatexshould handle this fine without doing anything special. Is the url in theurlfield of your bib entry? And is the format of theurlfield:\DeclareFieldFormat{url}{\url{#1}}(if you've modified it)? – David Purton Sep 04 '17 at 12:15
