Non-technical questions for landing a DevOps job in 2023

For soft skill questions, refer to this article on the Talent500 blog. But with the recession making things worse for everybody out there so here are a few answers to the ‘hard questions:’

Would you settle down on a lower pay than you just quoted given the recession?

While you may have to accept a TC lower than your expectations in many cases, you must negotiate on the below terms:

  • Ask for the position to be made a remote if it’s not already one since it will help you cut down on transportation costs.
  • Ask explicitly for considering appraisals with a higher (imaginary) payout since increments are calculated on the basis of the last drawn salary.
  • Demand higher ESOP payout with relaxations on maturity period and liquidity.
  • Ask the employer for more flexibility when it comes to leaving policy.

Such requests may not necessarily be met but they will surely indicate that you consider the opportunity important and that you aren’t a novice/gullible.

Given the state of the economy, why do you think that your expected TC is well justified?

During recessions, spending definitely slows down but it doesn’t mean that investments halt completely. As they say- safer bets like real estate and gold outperform commodities (unsafe bets) and over the past couple of months, I have upskilled myself in both technical and soft skills to ensure that I can deliver better value to my future organization. Hence, I believe that my willingness to deliver above and beyond makes me a safe bet in a seemingly ‘desperate’ job market.

Summing Up

Lastly, have a clear understanding of your past career trajectory and how you plan to move forward viz. vertical or horizontal, large corporation or a startup, new products or legacy products.

While interviewing for different companies can get hectic, keep yourself updated on DevOps and continue upskilling yourself

Though hiring has frozen across many tech companies, many organizations are still looking for talent to help them thrive in these testing times.
