Uber appeared set to hire Assaf Ronen, the former vice president of Amazon’s voice and natural user interface shopping, to lead its products — but it looks like that isn’t going to happen due to a discrepancy in his working history, according to Recode.

Uber discovered a discrepancy related to his tenure at Amazon, where the company appeared to be under the assumption he was working at Amazon at the time of offering him the job, and rescinded its offer, according to Recode. Ronen had actually left Amazon at the very end of 2017 and was not actually working at Amazon at the time, according to Recode, which posted a memo of new CEO Dara Khosrowshahi’s explanation of what happened. Ronen was brought in to take over the lead product role following the departure of former Twitter product lead and Google Maps exec Daniel Graf.

Since taking over, Khosrowshahi has tried to distance himself from the Uber under former CEO Travis Kalanick . Often times, CEOs will tell you that their number-one job is recruiting. Twitter CEO Jack Dorsey has mentioned it on a quarterly earnings call at least once a year for the past three years, for example, usually something to the extent of “my primary focus is on recruiting.” That’s obviously going to be a big tenet that will determine Khosrowshahi’s vision for the company and, ultimately, his legacy.

Current product VP Manik Gupta will be running the company’s product operations in the mean time, according to the memo obtained by Recode. Ronen would have been a marquee hire for Uber, but as the company has gone through a myriad of blunders under Kalanick, in addition to one of its autonomous vehicles being involved in an accident with a pedestrian on Monday, it looks like Uber is facing another hiccup in its turnaround at the top.

We reached out to Uber for additional comment and will update the story when we hear back.
