Bash scripting is not that easy and the hiring team must not be having an understanding of the subject. To hire any developer for the team, HRs are not required to learn the candidate’s subject of choice. Instead, they are recommended to use a few methods to choose a perfect employee. So, it is not at all necessary for the HRs or for the hiring team to have a hold on Bash scripting.
Then what to do if the HR lacks the subject information? How will they hire the most suitable fit for the company? Do not bother, we have got you covered. You would not need to by-heart the subject. You just have to go through some of the advanced Bash questions. Ask these questions to your candidate in the interview and just go through the answers to those interview questions from Google. This way, you might get closer to your ideal teammate.
Hiring your Bash developer simply on the grounds of his/her CV is not enough. Here are some of the things that you need to keep in mind while hiring a Bash Developer. Yes, skills and achievements are a bonus but they are not everything. Experience, technical hold, and soft skills are the real topics for the checklist.
Here are some of the things that you should keep in mind while hiring a Bash developer:
Understand For What You Are Hiring The Developer
Bash got its fame because it is an improved version of Bourne Shell. Bash Scripting is a must-skill for any Linux system administration job. But not all developers can use this scripting language wisely from start to end. So, depending upon the requirement of your company, you will have to hire your developer.
Make your goal, agenda, or the purpose of hiring the developer and make it clear to them what you expect from them. It will help them get a brief about their responsibility and you can also decide if they will match the role or not.
Look For Experienced Candidates
Experience is a must in any field. Your candidate might be having good skills and an attractive resume but what if they are not experienced enough to dwell in your company? So, it is completely necessary for the hiring team to look at the experience column and put a check on it.
Check Out On The Developer’s Communication Skills
Bash scripting is a bit complex but it is essential for the developer to possess excellent communication skills. This skill will help him/her to communicate with the customers or the organization with efficiency and express his/her ideas seamlessly. Problems and difficulties will also be delivered with ease.
Test The Technical Abilities
Make sure that your candidate is not just a bookworm. Check if he/she is technically sound or not. For the same, you can take a coding test of your applicant on any good online Bash code sandbox. This will help you in deciding if your candidate is worth the position or not. Scripting is not that easy and so it is not a subject that can be just mugged up on a theory base; practical knowledge is important.
You must check the professional skills of your applicant by making him or her code on any of the best remote coding interview tools and also place your interview questions before him/her.
