Transitioning into the online working environment could be tough, especially in a startup environment with not a lot of structure in place. I was able to quickly adapt within 2-3 weeks of work. However, that wasn't the case for some of our employees and interns.

To all startup founders and HR managers here on Hacker News, I would love to seek some advice on how you approach a situation like this. If you have any tips, guides, or even successful case study you have implemented for your company, i would love to further connect and learn more from you.
