Does BBA campus placements have aptitude test , etc for recruitment especially in marketing specialization?
See not only for BBA but for BTech/MBA/MCA placements also aptitude tests are organized by most of the companies. Most of the process starts with aptitude test followed by a Group discussion and then an interview. So yeah! you should prepare for Aptitude test as most companies will conduct it. In the aptitude test, logical reasoning question are the mostly present as well as there can simple problems of arithmetic. For Logical reasoning you may follow RS AGGARWAL book for Logical reasoning.
I hope this answer helps. All the very best for your future endeavors!
