We were descending via the ZZZZZX arrival with the Autopilot off - on profile and speed. FO decided to hand fly the remainder of the approach and landing and disconnected both the Autopilot and Autothrust near ZZZZZ1 intersection. A minute later I looked away and when I looked again; I noticed the FO was high on profile and I mentioned that we needed to cross ZZZZZ1 level at 6;000 feet. The FO increased the rate of descent and crossed ZZZZZ1 level at 6;000 but then continued to descend to approximately 5;900 feet and around 250 knots - with accelerating trend. I verbalized both altitude and speed; and the FO quickly recovered both. We were soon level at 6;000 feet - 240 knots...and soon to slow to 210 knots by ZZZZZ2. There was very light traffic in the terminal area and ATC made no mention of conflicts of any kind. We then proceeded to land uneventfully on Runway XX. The main contributing factor was the FO being new as well as not having flown much for the last several months. We fully debriefed everything; including what to improve on; once at the gate when duties permitted.
Air carrier Captain reported an altitude and airspeed deviation during arrival.  Captain cited the First Officer's lack of flying time in the last several months as a contributing factor.
