European Commission

In 2020, Seibert and von der Leyen were criticized for creating a large backlog of high-level and senior position vacancies at the Commission due to their insistence on having personal control over the appointments. Over 70 director, director general or deputy director general jobs were unfilled as well as over 80 mid-level positions. Over 21% of senior positions across departments were vacant in mid-October according to Politico. He has been criticized for his role as leader of von der Leyen's advisers due to them not taking much input from people outside this inner circle, including from her commissioners.

After Russia invaded Ukraine in 2022, Seibert was "critical" to the successful European negotiations with the United States regarding international sanctions on Russia. According to an EU diplomat cited by the Financial Times, he was "the only one that had an overview on the EU and in constant contact with the US".
