COVID-19 has negatively impacted almost all careers, and software engineering is no exception. However, a survey conducted by  Career Explorer  suggests that software engineers are faring better than other professionals. Among surveyed professionals across all industries and job titles, 20% of respondents have reported losing a job due to COVID-19. Among the survey respondents, software engineers experienced a 5% job loss. Also, 48% of all the surveyed professionals showed concern about job security. On the other hand, only 31% of software engineers highlighted the issue of job security. It is important to highlight here that the above software engineering job respondent data is taken from across the industrial spectrum. Engineers and developers working in different sectors may likely face contrasting situations. For instance, software engineers and developers working in the hospitality industry have to experience pay cuts and layoffs. On the other hand, engineers and develope...
