Bangladesh Public Service Commission (PSC) said a total of 412,532 candidates applied for 40th BCS.
This is a record in PSC history as there has never been such a huge number of applications in any competitive examination under the commission.
PSC chairman Mohammad Sadiq said the preliminary test of the 40th BCS may be taken in April this year.
The PSC published the 40th BCS notification on September 11 while the application submission started from September 30.
A total of 1,903 cadres will be recruited through the 40th BCS. But this number may increase later, said PSC sources.
