This question already has an answer here:
I work for a small company that has a very small development team. Before I joined the company was just the one senior developer who has been at the company for almost 10 years and designed and built the website. The website is business critical and it is how we make 99% of our income. I am a junior developer fresh out of college and this is my first job. I have fit in well and enjoy the work. Today I found out that the senior developer will be leaving in two weeks which has put me in the drivers seat of essentially everything from developing our new site and making sure the old one continues to work, to controlling the AWS server, local server, exchange server and a bunch of other things that I am not sure how to handle all on my own.
The owner and I have of course started discussing how we are going to replace the senior developer and since I am the only one who knows anything about development I am going to be conducting the interviews and looking at candidates. I feel like I am not even remotely qualified for the position that I have been put in. How do I go about conducting a technical interview when I myself am still learning not just our system but what it means to be a developer? I am hoping that we can fill the position before the senior developers last day but I want to be prepared for the likelihood that it will not happen since the pay at this company is pretty far below the averages for our area and many senior software developers wont want to take this sort of pay.
