Hi Vasudha,

SPJAT exam is conducted four times a year. The exam is usually conducted in April, May, June and July. Work experience is not mandatory for admission. However, the institute (SP Jain School of Global Management) does profile based shortlisting based on the academic background and relevant work experience. If you do not have work experience, you would need to write the SPJAT exam first, and then you will be called for evaluation rounds - Essay writing and panel interview. The exam for January 2019 intake has been conducted already. The dates for the next SPJAT exam will be released soon. You can visit the official website to stay updated for SPJAT dates. 

SPJAT is 1 hour online exam carrying 46 multiple choice questions. 

Hope that's helpful. All the best.
