DMS (Data Management Systems) Senior Software Engineer interview questions

A recruiter called me upon a recommendation, I interviewed with them, the interview process was silly. the whole process took one week. Firstly, you have to wear a formal dress code during the interview day. Then you will go through written exams as follows: 1- IQ Test 2- Silly English Exam, such as "on" or "in" or "at", etc. 3- OOP Exam. 4- SQL Database Exam. 5- Technology Exam, based on your position most likely ".Net" or "Java". The four exams should take around 2 hours. Then you should wait 30 min to attend the interview. In the interview, there was 2 Managers, the HR head, and a technical team leader. Starting from Managers questions, through the team leader, ends up with the "very routine" HR questions and accent. After that, I've been told to perform a long task in 4 days "a tiny project". I did the task with bonus points and I've shared it before the deadline and eventually, I got no feedback. After a couple of follow-ups emails, HR told me that he don't know the status of my application. It was just a waste of time, even without respect at the end.
