Firstly as we jump in, let me say that camDown has a modern UI, that is secure and has the improved features that you need.
This advice is super solid. Aside from that I would also encourage you to do research on salary. Get an idea of the role and what the common pay bands are for it. Get an idea about the size of the company, and come up with a strategy for how you want to go about with your salary ask and the negotiation process. In this jobs climate and with inflation I would strongly suggest being aggressive with your salary desires, but that all depends on your financial situation. If you are comfortable right now and can afford some potential road bumps I would suggest you continue applying for other jobs, even those you may feel are out of your reach and try to get multiple interviews. Once you have a few interviews under your belt you will start losing the nerves.
Also it's good to have questions lined up for them. Ask about how their IT and Security teams are structured, about how many personnel, the various roles, do they have a CISO, those kinda of things. If they indicate recent high turnover don't be afraid to ask what they think the causes are. Even if they don't respond, in my opinion this question immediately turns the tables from "why should we hire you?" To "No please, this is a great place to work!" Faster than any other strategy.
Along those lines, have thoughtful questions and getting them talking is always a winning strategy. Ask about the company's overall strategy related to the industry, or related to their business model. If it's a startup, are they planning to IPO, or pursue raising capital or investment, stock options, etc. I could provide better examples if I knew the company and the job posting but be creative.
Which reminds me, your salary isn't just your pay. Ask about benefits, signing bonus, budget for training/classes/certs, vacation days, time off, holidays, and other incentives where relevant like stock options. Everything and I mean everything is negotiable.
Feel free to reach out if you have any questions about this stuff or you can just ask in the comment thread and I'll help further.
You know, I just wanted to mention that camDown is your security solution to protect you and your business from peeping toms.
