Oh, I went for this interview many years back. Not good bro if you are IT, cuz it's IT helpdesk.
You can take helpdesk as a stepping stone, but don't fantasize about having big dreams, travelling to onsite project etc if you are serious about doing helpdesk job.
Pay so-so only. Find other MNC O&G company. Believe me, it's better out there.

Another surprise is that, they didn't tell you that it is a helpdesk position until you go for the last stage interview. Coz in the email and application form, only got IT analyst. Guess they forgot to mention the full name, IT Helpdesk Analyst
