Assistant Professor In Electronics And Communication Kerala PSC 2022: Exam Made Easy

Kerala PSC selects candidates for Assistant Professor in Electronics and Communication through a written exam of 100 marks. This concludes the first phase of the exam. The second phase is an interview where the professional knowledge of the candidates is tested. Only those who secured above the cut-off marks will be called for the interview. 

Once both the phases are over, a rank list is published from which the candidates will be chosen according to the available vacancy for Assistant Professor in electronics and communication.
