I found the vacancy and applied through LinkedIn. Soon enough an HR Manager contacted me, we discussed their roles and the company. Then they asked me to run a take-home task (a backend API solution), prior to any technical interview. It took me several days to complete it, basically, I did my best on this. I got no review feedback from them but standard "...As one of the leaders within our industry, we receive many qualified applicants like yourself". Don't waste your time on take-home assignments! They show only that the companies value their own time (so not offer technical interviews), not yours.
