Meraki Network Support Engineer interview questions

I applied online and was contacted by the recruiter. The recruiter scheduled a call with him to know about my current job role and area of interest. He asked a couple of technical questions like how DHCP works etc. The recruiter schooled a technical interview which was troubleshoot related. After I cleared that round, I had a sample writing round where I had to send an e-mail to a customer regarding the issue he was facing. After this I had another technical round. This round was also troubleshooting related. The interviewer game me a good feedback at the end, but because I don't have any experience in troubleshooting, I was rejected. The process is quite long, it took 1 month to complete 3 rounds and the final round is onsite. So the complete interview process is more than a month long (the onsite round has 4 interviews of 1 hr each).
