The job interview is a complete scam. They just want you to help them think and do their jobs. They also only want cheap staff. The first round is a take-home technical assignment (without even a single verbal or phone interview). After swiftly completed the assignment, they said thank you and said that they will process it. After a few days, upon checking, they told that they are still processing it and informed that the assignment was well done. After that, they scheduled subsequent interview. In the last 10 minutes before the interview, the HR cancelled the interview without giving reasons. Only upon calling and checking with them, the HR messaged me that the job is postponed until further notice. She did not even dare to speak to me verbally. The interview is a total con job and scam to exploit information from technical assignment. They also only want cheap staff. If you don't know how to do the job, don't offer your business to clients and upset your clients.
