Deel Support Engineer interview questions

The proccess was quick at the begining with a first initial interview and then a take-home test sent to me to finish within some days. I resolved the test and sent the results back to the company but never heard back since. When a company paints itself as a startup with new ideas and culture but don't bother to even provide a negative response/feedback to a hiring proccess it just appears that the company is not really a serious one.
