Techequity interview questions

It is an absolute waste of time and effort and an unprofessional approach by the company. Was approached by the CEO on linkedin in the month of March followed by a skype interview in April. Interviewed by a person(a client of the company) over skype for the first round of screening. Followed by a design assignment to be submitted under 2 days time. To my surprise, the person who took the skype round claimed to be a client of the company, turns out to be a friend of the owner confirmed by the HR. For the past 1 month, after several follow ups and emails, no feedback on the assignment submitted under 2 days of deadline.
