Planning to Apply? Consider this:
Make sure you go through this section very carefully before applying. Here are the most crucial aspects on which we evaluate on:
1: FIT: “We’re on a crusade for something greater than any one of us”!
We are a tight-knit team that works and plays together where ‘fit’ is the most important point that you need to keep in mind while evaluating us- we will be spending a majority of our time together, in office, on calls, even weekends (sometimes) so you’ll really need to assess whether this is the right place for YOU to be in. Are you able to relate to or feel passionate about the problems we’re solving?
2: INTENT: “You won’t just be working with us, you would be investing in us!”
‘Why’ do you want to work with us? Why an early stage startup? Why Original4Sure? We are an industrious team, working tirelessly to achieve our goals so the work hours will be long and with it will come with a steep learning curve. Joining an early stage startup also means you’ll be asked to take on new things with little guidance and you’ll have to figure stuff out on your own, and in doing so, help shape the future of the company. Does that sound scary, exciting, both?
3: CAPABILITY: “Get work done!”
As long as you are working as hard as you can and giving it your best all day, every day, we will get along just fine. No one ever built one of the most valuable businesses in the World without the core team having to make a few sacrifices along the journey. It could be lesser time spent with your family or loved ones or finding lesser time to do to watch TV shows! But that's a call you need to make.
