There was no interview process. I was sent an email from a Klook recruiter with information about a case study to complete over the weekend. I followed up to the recruiter with a receipt confirmation and no response to that. Afterwards, I've sent my presentation that I've worked on over the weekend, there was no response of receipt nor confirmation or rejection. Been waiting for a response from them, it's been a week but still no response. I think, for the company to ask you to spend some(weekend) of your time on a case study they asked you to complete, it's just professional to respond with a decline/proceed response from the company. Do you agree?
