After redshirting in 2011, Hundley was named the UCLA starting quarterback for the 2012 season.   In his first college game, against Rice, Hundley's first play was a 72-yard run for a touchdown that led to a 49–24 victory. In his second start against the No. 16 Nebraska Cornhuskers, Hundley had 305 passing yards and four touchdown passes as UCLA upset the Cornhuskers 36–30 in their home opener. Hundley also helped UCLA defeat the USC Trojans 38–28 for the first time since 2006, passing for 234 yards including 1 touchdown. In addition, Hundley ran for 2 touchdowns. The Bruins advanced to the Pac-12 Football Championship Game against Stanford, but were defeated 27–24. UCLA finished the season with a record of 9–5, and were ranked No. 17 by the Associated Press. Hundley set a school single season record with 3,740 yards passing. 
In 2013, Hundley led the Bruins to a 10-win season. The team beat USC, by a score of 35–14, marking consecutive wins over their crosstown rivals for the first time in over a decade.  UCLA won the Sun Bowl, 42–12, over Virginia Tech with Hundley being named the game's co- most valuable player with teammate Jordan Zumwalt. Hundley ran for 161 yards and two touchdowns on just 10 carries while also throwing for 226 yards and another two scores.  For the year, his 748 yards rushing were the school's third-most rushing yards in a season by a quarterback.  Two NFL teams told Adam Schefter of ESPN that Hundley was potentially the top quarterback of the 2014 NFL Draft if he left school early. However, Hundley elected to return for his junior year at UCLA.  Leading up to the draft, some scouts questioned Hundley's passing accuracy and decision making. 
Wary of the criticism of his passing skills, Hundley attempted to impress the pro scouts by running the ball less to begin the 2014 season.   The team began the season undefeated at 4–0 until the No. 8 Bruins were upset 30–28 by the Utah Utes. In the game, Hundley was sacked a career-high 10 times, renewing concerns over his pocket awareness.    Through 32 career games, he was sacked 107 times, the highest among active Football Bowl Subdivision quarterbacks.  Hundley eventually ran more, including 24 carries for a season-high 131 yards in a 17–7 win over Arizona.   Later in the season, he also became UCLA's all-time leader in touchdown passes, surpassing Cade McNown's record of 68;  McNown's record came in four years as a starter (1995–1998), while Hundley broke the record in just his third season.  Hundley also became the school's career leader in total offense, breaking McNown's previous mark of 11,285.  He was named to the All-Pac-12 second team.  He finished his career with 9,966 passing yards, second in school history behind McNown. He had also rushed for 1,747 career yards, behind only John Sciarra (1,813) among quarterbacks in UCLA history.

Hundley was drafted by the Green Bay Packers in the fifth round of the 2015 NFL Draft with the 147th overall pick.   On May 7, 2015, the Packers officially signed Hundley to a four-year deal.  He became the third-string quarterback on the depth chart behind Aaron Rodgers and Scott Tolzien. Despite attempting just ten passes in his rookie regular season, his success in the preseason and off-the-field maturity eventually led to his being named as the Packers' backup quarterback after Tolzien's departure.
During the first quarter of the Week 6 game against the Minnesota Vikings on October 15, 2017, Rodgers suffered a broken collarbone on a hit by Anthony Barr.  Hundley then entered the game, completing 18-of-33 passes for 157 yards, one touchdown, and three interceptions as the Packers lost by a score of 23–10. After the game, head coach Mike McCarthy stated that Hundley would take over as starter due to Rodgers's injury.  In his first start, he recorded 12 completions on 25 attempts for just 87 yards, zero touchdowns, an interception, and a passer rating under 40 for the second consecutive week, though he did contribute a 14-yard rushing touchdown. After a Week 8 bye, Hudley had 245 yards passing and a rushing touchdown in a loss to Detroit in Week 9. Week 10 continued this improvement, with 18 of 25 passing for 212 yards, 0 interceptions, and his first 100+ passer rating as a starter in a win over Chicago. He had 200+ passing yards for his third consecutive outing in Week 11, but no touchdowns against three interceptions in a shutout loss to Baltimore. In a Week 12 loss to the Steelers, Hundley played brilliantly with a 134 passer rating and three touchdowns, two of over 50 yards.  During Week 13 against the Tampa Bay Buccaneers, Hundley was held to only 84 passing yards and an interception. He rushed for 66 yards with the Packers combining for 199 rushing yards and winning 26-20 in overtime.
