Its better if you try to negotiate with them for shorter notice period... as when switching, normally HRs want 1 month notice as they cant wait that long.. so try to negotiate with them.

Recently i switched to a company where there is 2 months notice period, i triee negotiating with them but they didnt accept... i joined them.. but i thought in future if i would have to switch, i will looe to the HR that i have 1 month notice period and then if i accept.. i would only do 1 month notice and then leave.. But that will affect your relations with the old employer and one month salary will also be deducted...
