I loved how they helped me gradually learn and apply my skills over the 8 weeks. From the basics of learning version control with git, to working with JavaScript and ReactJS to put their APIs in use, it was a great experience.
What I wish was different
I wish they had mentioned what programming languages I would need to work with. I didn't know JavaScript or ReactJS, and spent a lot of time initially just learning them
Advice
It is never a waste to spend time online to learn skills related to your work/studies. Even if there is no internship in sight at the moment, work on learning newer things related to your field and get experience in mini-projects by yourself. It's okay to fail at that time, that's how you learn.
