Technical interview and assessments

[wijcc]

Does anyone have any advice/tips on technical interviews and assessments? I have after being in the same job for over 14 years been out of practice, also very nervous and do badly at interviews and exams. I am kinda of bricking it over what would be asked in these interviews and assessments.
How and what can I do to help and prepare for technical interviews and assessments?. I am looking and going for system admin & IT support roles.
Thanks in advance
