Candidates are advised to wear simple, comfortable clothing like T-shirts, shirts, and trousers without large buttons, pockets, or metallic trims. Footwear should be open (slippers or sandals), as closed shoes or thick-soled footwear are generally discouraged and may be subject to stricter security checks. Metallic items, including jewelry (earrings, rings, bracelets), watches (analog or digital), and electronic gadgets are strictly banned. Head coverings are not allowed unless for religious reasons.
