Write a linkedIn Message to ask a higher officer in company before joining asking about what all I have to prepare any tips or advice on what I should focus on or study for so that i can be well accustomed with the required skill sets for the job.
Hi [Manager] Sir,

I hope you're doing well!
Myself [My Name] from ITER, SOA University.

I just wanted to reach out to you before I start at [Company] in a month. I'm really excited to join the team and get started on my role as Intern Trainee Engineer- Platform. I was wondering if you had any tips or advice on what I should focus on or study before I start to make sure I'm as prepared as possible? I want to make sure I hit the ground running and make a good impression on the team.
Any suggestions would be greatly appreciated. Thank you for your time I'm looking forward to joining the team and working together!

Thanks,
[My Name]
