More than 90 persons have applied for the position which fell vacant after the sudden resignation of Chitra Ramkrishna in December.
Sources said the interview process is expected to start this week and there are around eight to ten candidates in serious contention for the top post at the country's largest bourse.
Those believed to be considered include former BSE chief Madhu Kannan and commodity exchange MCX MD and CEO Mrugank Paranjape, sources said.
"Mrugank Paranjape is not in the race for NSE's MD & CEO. MCX vehemently denies this," the exchange said in a statement.
