After departing; with the Captain as PF (Pilot Flying) and while climbing through approximately FL200; the aircraft experienced a violent shudder followed by an ENG 2 STALL ECAM message. Approximately 20 seconds later; a second ECAM; ENG 2 EGT OVERLIMIT was displayed. Both ECAM advisories were intermittent. After following ECAM Methodology; we transferred controls; I was now PF and handling the radios. The number2 engine did not respond to throttle movement and it appeared to be in a failed state. As there is no procedure for an ENG 2 STALL ECAM; and the ENG 2 EGT OVERLIMIT ECAM was no longer displayed; the Captain elected to run the ENGINE 2 FAIL procedure in the QRH. I [notified] ATC and requested diversion back to [the departure airport]. We were extremely rushed as we were only about 50nm from the airport. Upon completion of the QRH procedure; we again transferred controls and the Captain was the PF with me handling the radios. We briefed the ILS approach; completed the normal approach checklist; and landed without incident. Immediately after exiting the runway; we shut down the number2 engine.
