Ventajas
One can apply for as short as 1 month and get a flavor of how start ups work and what kinds of clients come in day to day life. Beneficial for someone who wants to start their own start up.
Desventajas
Since it's an unpaid internship the incharges take your advantage and give you all sorts of work even if it is not related to your domain. They take money from their clients and then force us to like their webpages, review 5 stars and download apps and games from unsafe portals. Not just that they harass you into getting you to get your friends to do it too. They have a very casual attitude towards work. They ask you to post stuff about them on social media even if you don't want to. They will get you attend unnecessary live podcasts, every day, 3 times, just to increase the viewership and earn money for themselves. The podcasts are not even remotely useful for your domain most of the times.
