Interview at LeanPlum. There were 1 technical phone screen + 5 interviews onsite. I had a very bad experience interviewing with this company. Since the interviews went pretty fine and I thought I had a chance of getting an offer. But they never got back to me regarding the results. I waited for a while and then emailed them multiple times. They never bothered to reply. Offering a job or not is completely up to the company. But companies should respect the fact that people take time out of their lives for these interviews. I read that a lot of people had similar experience with this company. So it is safe to say that it was not a one time thing. The company clearly doesn't care about the candidates' time or effort. Stay away from LeanPlum.
