Kleboe Jardine interview questions

I applied for a job advertised by Kleboe Jardine. After a call with them, they sent me some activities to evaluate my technical skills. I spent about 8 hours working on the activities and send them back to Kleboe Jardine. After two months, I haven't received any response about the job application, even though I tried to contact them by phone and email. I feel I have wasted a lot of time with this organisation so I do not recommend applying for jobs with them.
