Applied through LinkedIn in May 2022 and HR contacted me after a week of submission of the application. 45 minutes interview with the Hiring manager. 4 hours of interviews with technical expertise. HR confirmed I am selected and going to release the offer letter. Afterward neither communication nor an offer letter. Later on from various online platforms it's understood that they going through massive layoffs and that is quite understandable. Companies sometimes used to go through touch phases but they should have maintained some courtesy to the candidates by stating this time they are not releasing the offer letter due to market instability and considering in future.
