Pros

Not that much to say, except some very nice colleges

Cons

I was reading these positive comments in 22, and based on my experience and many colleges, Callsign is putting false reviews, trying to do what they know the best to lie The company is having a problem with the product, it's all lies, non existing capabilities, no one need it or want it. Also huge problem with management, people first time at this high level positions not sure what to do. Almost all management comes from big banking organisations, and you know how things are political and slow, and in Callsign, they implement the worst form of management CEO and in general all CxO board are without skills and full of lies.

Pros

Product is interesting and has good buzz in the market. Company has/had some talented engineers

Cons

They expanded their business hugely in 2020 -21 and did alot of hiring but in 2022 Q2-Q3 the CEO started FIRING some excellent employees randomly. No proper reasoning, no proper communications was done around company roadmap or firing and now everyone is living in dilemma. Honestly, I wanted to give 0 star but thats not the option in glassdoor

Pros

None I can honestly stand by

Cons

A CEO that is an former security architect with no real experience or strategic vision of where the company and product is going, they also like to hire all their old buddies who have little to no industry background or experience but massive egos and any new employee gets treated like an outcast and very isolated, a company to join if you want to swiftly learn how not to run a company and overstate a products capabilities

Callsign Response

Hi, We are really worried. You are a current employee who has raised issues about feeling isolated. Please, please contact me in confidence, you will know from the job title written here who I am. I am here to ensure your welfare. To anyone else reading this, we are not going to comment on what is raised because this is an employee who has said they feel like an outcast and any comment may exacerbate this feeling.
