Interview preparation tips for other job seekers - I would strongly advice job seekers to avoid engaging further with this company. Based on my experience, their process lacks transparency and respect for candidates time, with poor communication and unclear criteria like 'culture fit' only being raised after multiple technical rounds. SAVE YOUR TIME and ENERGY by skipping this opportunity.

Interview Preparation Tips

Interview preparation tips for other job seekers - When I was cleared my all round of interview and then HR comes to me and said 'congratulations you are selected ' and please come tomorrow for the documentation. Tomorrow the HR assign me the task of assessment, that was not acceptable 😑 because I was cleared my all round off interview and they told me to come for the documentation. On the last day I was resigned my last company because I got selected. But this situation is very difficult for me whether I failed assessment then they reject me. I did my assessment and have cleared 🙌 and then they told me for typing test which results is passes and then they started the documentation. It takes approx 21 days to get offer letter.
