You do not get anywhere near 40 hours a week. I averaged almost 6 (six!) hours per week over the year I worked with them.
They rope you in saying you will make $40 an hour. In fact, they require you to be ready to work 40 hours a week even if theres nothing to do. The majority of time, all of the web devs were sitting there doing nothing.
You do not get paid for mandatory company meetings. Should have been a red flag.
They did not pay me for work I did in March of 2016, and now its Dec. It was the owners friends site, which should have been a big red flag.
They want you to go to a yearly development 'convention'. You make $200 a week from them and then are expected to take a week off and then pay for your own airfare? No. Another red flag : cheapness.
This is a filemaker shop 100% that wants to dabble in web dev, but there are no, and I mean no, systems in place for web development. No unit testing, no QA, no build tools, no agile development, nothing like a sprint, no scrums, no real use of git (they think its just for backups), they still host on godaddy and have no idea what node is or why its important. Minifying js and css? Hah! Not here. They resist change. There is a dearth of javascript and PHP skills. Everything is pretty much depending on one talented developer.
This is a filemaker shop that seems afraid filemaker may someday be obsolete so is desperately flailing around thinking it can fake it as a web dev company. Stick to filemaker or invest in infrastructure.
