Suspicious company - Software Engineer EX² Outcoding Employee Review

Don't EVER accept any "opportunities" coming from this company. They take advantage of unemployed people in order to get free work/consulting. 5 weeks of selection process to simply cancel the interview 1 week earlier. They asked me to build an app from scratch even telling me to change the designs to simply cancel all the process. You should be ASHAMED of yourselves. In times of crisis in the job market, people (and also companies) really review who they really are. If care about your carrier, time and money; i suggest to STAY away and try to find work somewhere else.
