The Patriarch of Constantinople is chosen through a process that usually involves the Holy Synod of the Ecumenical Patriarchate. After the death or resignation of a patriarch, the synod convenes to elect a successor, typically from among the senior bishops or metropolitans. The election process often includes nominations, discussions, and a vote by the synod members, ensuring that the chosen candidate has the necessary theological and administrative qualifications. Once elected, the new patriarch is confirmed by the synod and formally installed in a ceremonial manner.

I am Orthodox, but I am not intimate with the details of the process. As I understand, the candidates are chosen by the Church, both clergy and laity. In most if not all jurisdictions, for the "inauguration" so to speak, an elected bishop must profess the entire faith before three other bishops, no two of whom are from the same archdiocese. The idea is that what makes him worthy of the office is not the "magic hand" of an apostolic line, but his profession of the Orthodox faith, coupled with the grace of Christ. I imagine this happens in patriarchal elections too. A candidate is chosen by the members of the Holy Synod of each jurisdiction For example, the Holy Synod of Russia elects the Patriarch of Moscow, and the Holy Synod in Constantinople elects the Ecumenical Patriarch. The lay people must also approve the election of all bishops (including patriarchs as they are also bishops).
