Life as a Leanplum Intern

Learn what it is like to do an internship with us from Denis Hristov, Software Engineer II at Leanplum: „The experience was one of a kind! Everyone was quite welcoming and joyful. Getting to know the company's culture was the best part since I resonated a lot with it. The cool thing was that it did not really feel like an internship since I was solving real problems just like everyone else and colleagues valued my opinions and views.“
