I applied for a job on LinkedIn and they asked me to prove my skills by taking a test. I passed the test and moved on to the next round, which was an interview. During the interview, they asked about my previous work experiences and projects. I did well in the interview and they contacted me later to discuss my salary expectations. I told them my desired salary and they said they would email me once my offer was approved by the head office. However, I haven't received any email from them and they're not responding to my messages or emails.
