The ones who get more work r usually the ones who gets evicted early! Best examples Sunny Leone and Nora Fatehi but they r not from acting industry. Besides that it has not benefit the actors/actress much post the show. One exception is Hina who also went far in the show and an TV actress too.
From this season, I actually noticed Shardul and Nishant r getting decent work for now so far compared to others even though they didn’t get much stardom from the show. Shardul is back to his radio jockey job, and even most of the tv celebs r promoting him. I m glad that Shardul is getting work because he needs it the most!Nishant also got 2 web series, one he already finished shooting, and another he just started shooting. Plus they both got unfairly evicted so I m glad it worked out well for them. As for Rubinav, Rahul, Aly, i think its still too early to say for them as they just got out of the house so probably talks maybe going on.
Music videos take 1-3 days to shoot so thats why most of these contestants get to work in more music videos and also it doesnt take much effort for acting compared to other projects.
As for last season ones, I think Shehnaz and Asim got a lot from the show, Shehnaz is very famous now, that viral video from Yashraj helped even more, she also got a movie recently. Asim made most impact internationally, he is actually working with DJ snake(no joke). Lets see if they can maintain their stardom. Himanshi turned out to be the dark horse in terms of gaining stardom through BB13, she also got a lot. Rashmi n Sid got a web series too if i m not wrong. So I dont think its that bad. If i m not wrong Madhurima did a movie too and got an award after getting evicted.
