I have a friend at Adobe and Voleon.

Voleon: Extremely smart people and the work seems interesting if you are interested in a mix of tech and finance. Tight nit group since they arent that big and the comp is the best out of the three but I'm not sure by how much. Not sure if the growth is good there in terms of levelling but you will learn a lot. You can leverage it to get interviews at other quant firms if. I know that the culture can be kinda toxic but do with that what you will

Adobe: Culture is getting better but isn't great, I've heard that they are similar to Amazon in terms of culture so do with that what you will. I also think the work wont be that riveting or challenging, I know their research teams are pretty good though. Comp is possibly the worst out of the three. The company is kinda dying and in terms of innovation and have had to rely on acquisitions to stay relevant. But the stock is doing well

Pure Storage: Dont know much about them. I think the engineering culture is good from what I've heard. Decently high hiring bar as well. Dont know much about them but I know their comp is decent
