This is a job scam that lures users using big organization names such as ‘UNICEF’ in this case. The same phish has also been observed with different subjects such as ‘internship Opportunity’, ‘Paid engagement internship!’ or maybe more.
Although, it is a well written and well-structured email but still the warning signs remain the same as with usual phishes. The sender email address is not on UNICEF domain, generic salutation and no signature. The job posting mentions about a job that starts from January but we are already at the end of February, which is a big red flag.
