What people at JFrog say
Reviews originally posted on Glassdoor.
Team's attitude towards helping each other out is the important aspect I value the most and haven't experienced in my past.
jfrog is a company made up of lots of talented, smart, passionate people. the technology is first-rate, our developers are brilliant, and i strongly believe in the market for the jfrog suite of products. artifactory and bintray are going to live on, in some form or another. much of what is being developed there will define this space for devops needing CI / CD solutions
Work life balance, Interesting technologies, Challenging day to day work, Good Environment. The culture is great at the office. A place where you can not only improve your work life, but also improve yourself as a person.
Fake reviews posted by people. Those who are joining watch out. PLEASE TAKE THIS ADVICE SERIOUSLY. The company people are pumping up glassdoor ratings.
