We will present a Chevet-type inequality for subexpontial Weibull processes and show how it may be applied to find two-sided bounds for operator \ell_p to \ell_q norms of random rectangular matrices with iid Weibull entries. We will also discuss lower and upper bounds for operator norms of other iid matrices. The talk will be based on a work in progress with Marta Strzelecka.
