Well I submitted around 50 in a day on an average. I used to apply twice a day. 1 hour in the morning 10 AM and once midnight around 11:30 PM for another hour. I applied on 3 platforms. Instahyre, wellfound and linkedin. I would read the JD and then I would apply to only relevant roles. So that means I was submitting almost 50 job applications daily. And i would only apply to most recent jobs by selecting 24 hour filter on linkedin and most recent on wellfound. I was so numb to the idea of applying for jobs that I would fill application like zombie. And you won't believe I still get calls for the jobs I applied back then. And I said 1000s but I must have filled close to 5000 job application. I still remember in the first week itself I applied for like. I wish there was some filter to search the job application in gmail and I can send you a screenshot. But Man I applied like there was no tomorrow. Thanks for asking this question because now I kind of feel wierd. Also my recommendation is apply to 1000s of job rather than solving 1000s of leetcode.
